Circa 2011
320 million years ago, mammals and reptiles reached an evolutionary parting of the ways. We’ve now sequenced a lizard genome for the first time ever, and it’s vastly different from our own…but in a few crucial ways, it’s shockingly similar.
Quantum illumination uses entangled signal-idler photon pairs to boost the detection efficiency of low-reflectivity objects in environments with bright thermal noise. Its advantage is particularly evident at low signal powers, a promising feature for applications such as noninvasive biomedical scanning or low-power short-range radar. Here, we experimentally investigate the concept of quantum illumination at microwave frequencies. We generate entangled fields to illuminate a room-temperature object at a distance of 1 m in a free-space detection setup. We implement a digital phase-conjugate receiver based on linear quadrature measurements that outperforms a symmetric classical noise radar in the same conditions, despite the entanglement-breaking signal path. Starting from experimental data, we also simulate the case of perfect idler photon number detection, which results in a quantum advantage compared with the relative classical benchmark. Our results highlight the opportunities and challenges in the way toward a first room-temperature application of microwave quantum circuits.
Quantum sensing is well developed for photonic applications (1) in line with other advanced areas of quantum information (2–5). Quantum optics has been, so far, the most natural and convenient setting for implementing the majority of protocols in quantum communication, cryptography, and metrology (6). The situation is different at longer wavelengths, such as tetrahertz or microwaves, for which the current variety of quantum technologies is more limited and confined to cryogenic environments. With the exception of superconducting quantum processing (7), no microwave quanta are typically used for applications such as sensing and communication. For these tasks, high-energy and low-loss optical and telecom frequency signals represent the first choice and form the communication backbone in the future vision of a hybrid quantum internet (8–10).
Despite this general picture, there are applications of quantum sensing that are naturally embedded in the microwave regime. This is exactly the case with quantum illumination (QI) (11–17) for its remarkable robustness to background noise, which, at room temperature, amounts to ∼103 thermal quanta per mode at a few gigahertz. In QI, the aim is to detect a low-reflectivity object in the presence of very bright thermal noise. This is accomplished by probing the target with less than one entangled photon per mode, in a stealthy noninvasive fashion, which is impossible to reproduce with classical means. In the Gaussian QI protocol (12), the light is prepared in a two-mode squeezed vacuum state with the signal mode sent to probe the target, while the idler mode is kept at the receiver.
Instead of shutting down, Sweden opted for much milder measures to stop the spread of the coronavirus. The idea looked appealing, with the possibility of containing the pandemic at a much lower economic cost. So far, however, the statistics suggest the Swedish model is more disaster than panacea.
Brain injuries can vary greatly in their severity, but assessing the extent of the damage is far from a simple undertaking. Scientists in the UK have developed a new AI algorithm that could help narrow the margin for error, with the ability to detect and categorize different types of brain lesions to gauge the impact of an injury.
One of the tools doctors use to assess brain injuries is a CT scan, which can reveal signs of damage, such as lesions, on the brain. But analyzing these scans to reach a diagnosis is a time-consuming process for radiologists, and given the complex nature of the organ, it can see tell-tale signs often overlooked.
“CT is an incredibly important diagnostic tool, but it’s rarely used quantitatively,” said Professor David Menon, from the University of Cambridge and senior author of the new study. “Often, much of the rich information available in a CT scan is missed, and as researchers, we know that the type, volume and location of a lesion on the brain are important to patient outcomes.”
“A wealth of information creates a poverty of attention,” said Andy McMurray, co-founder and CIO of Medal, an AI-based software company developing tools for health care, during an interview with Healthcare IT News.
This is especially true in the operating room, where surgery teams at the University of Iowa Hospital have reduced surgical site infection by 74% using DASH Analytics’ high-definition care platform (HDCP). This system observes data from the operation in real time and compares it to a patient’s history and its own infection models. Toward the end of the procedure, it automatically provides the surgeon with recommendations to reduce infection during wound closure. Furthermore, it notes whether the surgeon follows its suggestions or not and compares that to the outcome of the patient. This information is then used to both improve its infection model and improve the surgeon’s own performance in future surgeries.
Advances in AI build off of each other. One breakthrough opens the doors for more possibilities in the future, which in turn leads to even more breakthroughs at an exponential rate. Just as the Industrial Revolution automated back-breaking physical labor, the AI Revolution is poised to automate mind-numbing mental labor. Based on what we’ve seen in the last 10 years alone, we can expect to see this boom very soon.
The stem cell treatment is derived from human placentas and is being developed by New Jersey biotech company Celularity. The early-stage trial will include up to 86 coronavirus patients with symptoms who will receive infusions of the stem cell therapy to assess the its safety and whether it prevents the patients from developing more severe illness, The New York Times.
The stem cells from the placenta used in this treatment are “natural killer” cells that guard a developing fetus or newborn from viruses in the mother. Celularity has been testing this treatment approach in cancer patients.
Initial results from the early trial are expected 30 to 60 days after the first patients receive their dose, Dr. Robert Hariri, Celularity’s founder and chief executive, told The Times.
Ira Pastor, ideaXme life sciences ambassador and founder of Bioquark, interviews Dr. Robert Hariri, MD, PhD, surgeon, bio-medical scientist and highly successful serial entrepreneur in two technology sectors: bio-medicine and aerospace.
Dr. hariri utilizes biomedicine to aid human longevity:
Dr. Hariri is Chairman, Founder, and CEO, of Celularity, Inc., a clinical-stage cell therapeutics company developing allogeneic cellular therapies, engineered from the postpartum human placenta, in cancer immuno-therapy and functional regeneration, which recently got initial clearance from the U.S. Food and Drug Administration (FDA) to begin early-stage clinical trials on a potential treatment for Covid-19.
Dr. Hariri is also Co-Founder and Vice Chairman, of Human Longevity, Inc., a company merging extensive amounts of human genotype and phenotype data with machine learning, so that it can help develop new ways to fight diseases associated with aging.
Dr. Hariri served as Chairman, Founder, Chief Scientific Officer, and Chief Executive Officer of Celgene Cellular Therapeutics (acquired by Bristol Myers Squibb), one of the world’s largest human cellular therapeutics companies, where he pioneered the use of stem cells to treat a range of life threatening diseases and has made transformative contributions in the field of tissue engineering.
Recognition, Awards and Accolades:
US President Barack Obama called the Ebola outbreak in West Africa a threat to global security on Tuesday and broadly expanded the US response by ordering thousands of troops to the region along with an aggressive effort to train health care workers and build treatment centres.
He called on other countries to quickly provide more helpers, supplies and money.
“If the outbreak is not stopped now, we could be looking at hundreds of thousands of people affected, with profound economic, political and security implications for all of us,” Obama declared after briefings at the Centers for Disease Control and Prevention in Atlanta.
Obama acted under pressure from regional leaders and international aid organisations who pleaded for a heightened US role in confronting the deadly virus, especially in the hardest-hit countries of Liberia, Sierra Leone and Guinea.
“In West Africa, Ebola is now an epidemic,” Obama said.
“It’s spiralling out of control, it is getting worse.“
The stepped-up US response includes sending 3,000 troops to the region, including medics and corpsmen for treatment and training, engineers to help build treatment facilities and logistics specialists to assist in patient transportation.
Obama also announced that Major General Darryl Williams, head of US Army Africa, will head a military command centre based in Liberia.
The announcement came the same day the World Health Organisation warned that the number of West African Ebola cases could begin doubling every three weeks and that the crisis could end up costing nearly 1 billion US Dollars to contain.
Nearly 5,000 people have become ill from Ebola in Liberia, Sierra Leone, Guinea, Nigeria and Senegal since it was first recognised in March.
The World Health Organisation says it anticipates the figure could rise to more than 20,000.
Obama described task ahead as “daunting” but said what gives him hope is that “the world knows how to fight this disease.“

In US news and current events today, listen to Pres. Bush urgently stress the importance of being prepared for a pandemic back in 2005. In this clip, Pres. George W. Bush addressed the Nat’l Institutes of Health about having a game plan to fight future pandemics. Pres. Bush was reportedly alarmed after reading a history book about the 1918 flu pandemic where millions had died. Out of that interest came a grand outline for future administrations to follow in response to a global pandemic.
Listening in the audience that day was Dr. Anthony Fauci, dir. of the Nat’l Institute of Allergy and Infectious Diseases and current leader in the fight against COVID-19 today.
