A team of scientists from MIT and Rice University recently discovered a new method for creating qubits that could revolutionize both quantum computing and cancer research – and all it takes is some household bleach and a UV light.
Qubits are the basic units of information used in quantum computing. Typically, when scientists create them they go through a complex process involving lasers or shearing single photons off of light using complex, difficult-to-work-with reactants that produce unwanted side-effects. These time consuming methods often require trial-and-error and seldom produce perfect results.
Supergravity is described in the prize announcement as a theory in which, “quantum variables are part of the description of the geometry of spacetime.”
Two independent research teams recently published studies indicating they’ve successfully teleported a qutrit — possibly within days of each other. Now, both await the scientific process of peer review to see which will ultimately get credit for being the first humans to do so.
But what’s a qutrit? It’s a lot like a qubit, an entangled pair of particles used to carry information in a quantum computing system. Qubits are analogous to bits, the binary units of information used by classical computers like the one you’re reading this on. Where bits can be represented by the numbers zero and one, qubits can be zero, one, or both at the same time. Trits, used in classical ternary systems, add a two into the mix. And qutrits are the quantum version of trits, capable of carrying more information than their qubit counterparts.
Researchers at the Massachusetts Institute of Technology (MIT) have recently developed a metric that can be used to capture the space of collider events based on the earth mover’s distance (EMD), a measure used to evaluate dissimilarity between two multi-dimensional probability distributions. The metric they proposed, outlined in a paper published in Physical Review Letters, could enable the development of new powerful tools to analyze and visualize collider data, which do not rely on a choice of observables.
“Our research is motivated by a remarkably simple question: When are two particle collisions similar?” Eric Metodiev, one of the researchers who carried out the study, told Phys.org. “At the Large Hadron Collider (LHC), protons are smashed together at extremely high energies and each collision produces a complex mosaic of particles. Two collider events can look similar, even if they consist of different numbers and types of particles. This is analogous to how two mosaics can look similar, even if they are made up of different numbers and colors of tiles.”
In their study, Metodiev and his colleagues set out to capture the similarity between collider events in a way that is conceptually useful for particle physics. To do this, they employed a strategy that merges ideas related to optimal transport theory, which is often used to develop cutting-edge image recognition tools, with insights from quantum field theory, a construct that describes fundamental particle interactions.
Many phenomena of the natural world evidence symmetries in their dynamic evolution which help researchers to better understand a system’s inner mechanism. In quantum physics, however, these symmetries are not always achieved. In laboratory experiments with ultracold lithium atoms, researchers from the Center for Quantum Dynamics at Heidelberg University have proven for the first time the theoretically predicted deviation from classical symmetry. Their results were published in the journal Science.
“In the world of classical physics, the energy of an ideal gas rises proportionally with the pressure applied. This is a direct consequence of scale symmetry, and the same relation is true in every scale invariant system. In the world of quantum mechanics, however, the interactions between the quantum particles can become so strong that this classical scale symmetry no longer applies,” explains Associate Professor Dr. Tilman Enss from the Institute for Theoretical Physics. His research group collaborated with Professor Dr. Selim Jochim’s group at the Institute for Physics.
In their experiments, the researchers studied the behaviour of an ultracold, superfluid gas of lithium atoms. When the gas is moved out of its equilibrium state, it starts to repeatedly expand and contract in a “breathing” motion. Unlike classical particles, these quantum particles can bind into pairs and, as a result, the superfluid becomes stiffer the more it is compressed. The group headed by primary authors Dr. Puneet Murthy and Dr. Nicolo Defenu—colleagues of Prof. Jochim and Dr. Enss—observed this deviation from classical scale symmetry and thereby directly verified the quantum nature of this system. The researchers report that this effect gives a better insight into the behaviour of systems with similar properties such as graphene or superconductors, which have no electrical resistance when they are cooled below a certain critical temperature.
New research centering around the Unruh effect has created a set of necessary conditions that theories of quantum gravity must meet.
Quantum physics has, since its development in the early years of the 20th century, become one of the most successful and well-evidenced areas of science. But, despite all of its successes and experimental triumphs, there is a shadow that hangs over it.
Despite successfully integrating electromagnetic, the weak and strong nuclear forces — three of the four fundamental forces — quantum physics is yet to find a place for gravity.
This video is the ninth in a multi-part series discussing computing and the second discussing non-classical computing. In this video, we’ll be discussing what quantum computing is, how it works and the impact it will have on the field of computing.
[0:28–6:14] Starting off we’ll discuss, what quantum computing is, more specifically — the basics of quantum mechanics and how quantum algorithms will run on quantum computers.
[6:14–9:42] Following that we’ll look at, the impact quantum computing will bring over classical computers in terms of the P vs NP problem and optimization problems and how this is correlated with AI.
[9:42–14:00] To conclude we’ll discuss, current quantum computing initiatives to reach quantum supremacy and ways you can access the power of quantum computers now!

Ira Pastor Comments:
On the last several shows we have spent time on different hierarchical levels the biologic-architecture of the life, disease and aging process. We’ve spent some time talking about the genome, the microbiome, tissue engineering, systems biology, and dabbled a bit in the areas of quantum biology, organism hydro-dynamics, and even chronobiology. As exciting and promising as all these research paths are, at the end of the day, in order for them to yield what many people are looking for, that is radically extended healthspans and lifespans, there needs to be an organized system of human translation build around them, integrating these various products, services and technologies, from supplements, to biologics, to functional foods, to cosmeceuticals, to various physio-therapeutic interventions, and so forth, as well as all the related supporting advocacy and education, as biologic aging is truly a multi-factorial, combinatorial process that is never going to be amenable to big pharma’s traditional “single magic bullet” philosophy that it promoted throughout the last century.
For today’s guest, I could think of no one better to talk with us about this topic and take us into the future on this front, than Bill Faloon, Director and Co-Founder, Life Extension Foundation (LEF), a consumer advocacy organization with over 100,000 members that funds research (investing million per year in researchers around the globe) and disseminates information to consumers about optimal health, and more recently in the area of actionable clinical interventions regarding human biologic age reversal, through a fascinating new project called the Age Reversal Network, defined as an open-source communications channel to exchange scientific information, foster strategic alliances, and support biomedical endeavors aimed at reversing degenerative aging.
Bill is also the Founder of The Church Of Perpetual Life, a nonprofit transhumanist organization aiming to combine discussion integrating spirituality, community, and aging scientific research in a single unified forum.
He’s a board member of the Coalition For Radical Life Extension, which is the organizer of annual RAADfest conference (Revolution Against Aging and Death) which is the world’s largest gathering of radical life extension enthusiasts.
It’s time to celebrate another first in the field of quantum physics: scientists have been able to ‘teleport’ a qutrit, or a piece of quantum information based on three states, opening up a whole host of new possibilities for quantum computing and communication.
Up until now, quantum teleportation has only been managed with qubits, albeit over impressively long distances. A new proof-of-concept study suggests future quantum networks will be able to carry much more data and with less interference than we thought.
If you’re new to the idea of qutrits, first let’s take a step back. Simply put, the small data units we know as bits in classical computing can be in one of two states: a 0 or a 1. But in quantum computing, we have the qubit, which can be both a 0 and 1 at the same time (known as superposition).
