This tiny glass bead has been quantum chilled to near absolute zero

Posted by in categories: particle physics, quantum physics

A new method for manipulating the quantum state of particles could one day allow us to observe an object in two places at once. The technique has been used to chill a tiny glass bead into its coldest possible quantum state.

Once you get down to extremely small scales, heat and motion are interchangeable: the more a particle is moving, the hotter it is. So to cool down a small particle, you have to stop it moving. Because the rules of quantum mechanics mean you can never know exactly how fast a particle is moving, there is a limit to how cold a particle can get. When a particle is at that limit, we call it the particle’s ground state.

Technological Applications of the Higgs Boson

Posted by in categories: particle physics, quantum physics

Essentially the higgs boson could create a replicator and even a teleportation device.


Can you think of any? Here’s what I mean. When we set about justifying basic research in fundamental science, we tend to offer multiple rationales. One (the easy and most obviously legitimate one) is that we’re simply curious about how the world works, and discovery is its own reward. But often we trot out another one: the claim that applied research and real technological advances very often spring from basic research with no specific technological goal. Faraday wasn’t thinking of electronic gizmos when he helped pioneer modern electromagnetism, and the inventors of quantum mechanics weren’t thinking of semiconductors and lasers. They just wanted to figure out how nature works, and the applications came later.

Quantum computers offer another look at classic physics concepts

Posted by in categories: particle physics, quantum physics, supercomputing

“Think what we can do if we teach a quantum computer to do statistical mechanics,” posed Michael McGuigan, a computational scientist with the Computational Science Initiative at the U.S. Department of Energy’s Brookhaven National Laboratory.

At the time, McGuigan was reflecting on Ludwig Boltzmann and how the renowned physicist had to vigorously defend his theories of . Boltzmann, who proffered his ideas about how atomic properties determine physical properties of matter in the late 19th century, had one extraordinarily huge hurdle: atoms were not even proven to exist at the time. Fatigue and discouragement stemming from his peers not accepting his views on atoms and physics forever haunted Boltzmann.

Today, Boltzmann’s factor, which calculates the probability that a system of particles can be found in a specific energy state relative to zero energy, is widely used in physics. For example, Boltzmann’s factor is used to perform calculations on the world’s largest supercomputers to study the behavior of atoms, molecules, and the quark “soup” discovered using facilities such as the Relativistic Heavy Ion Collider located at Brookhaven Lab and the Large Hadron Collider at CERN.

Quantum experiments explore power of light for communications, computing

Posted by in categories: cybercrime/malcode, quantum physics

A team from the Department of Energy’s Oak Ridge National Laboratory has conducted a series of experiments to gain a better understanding of quantum mechanics and pursue advances in quantum networking and quantum computing, which could lead to practical applications in cybersecurity and other areas.

ORNL quantum researchers Joseph Lukens, Pavel Lougovski, Brian Williams, and Nicholas Peters—along with collaborators from Purdue University and the Technological University of Pereira in Colombia—summarized results from several of their recent academic papers in a special issue of the Optical Society’s Optics & Photonics News, which showcased some of the most significant results from optics-related research in 2019. Their entry was one of 30 selected for publication from a pool of 91.

Conventional computer “bits” have a value of either 0 or 1, but quantum bits, called “qubits,” can exist in a superposition of quantum states labeled 0 and 1. This ability makes promising for transmitting, processing, storing, and encrypting vast amounts of information at unprecedented speeds.

IBM And University Of Tokyo Launch Quantum Computing Initiative For Japan

Posted by in categories: computing, education, government, information science, quantum physics

IBM and the University of Tokyo will form the Japan – IBM Quantum Partnership, a broad national partnership framework in which other universities, industry, and government can engage. The partnership will have three tracks of engagement: one focused on the development of quantum applications with industry; another on quantum computing system technology development; and the third focused on advancing the state of quantum science and education.

Under the agreement, an IBM Q System One, owned and operated by IBM, will be installed in an IBM facility in Japan. It will be the first installation of its kind in the region and only the third in the world following the United States and Germany. The Q System One will be used to advance research in quantum algorithms, applications and software, with the goal of developing the first practical applications of quantum computing.

IBM and the University of Tokyo will also create a first-of-a-kind quantum system technology center for the development of hardware components and technologies that will be used in next generation quantum computers. The center will include a laboratory facility to develop and test novel hardware components for quantum computing, including advanced cryogenic and microwave test capabilities.

Quantum computing talent war: JPMorgan Chase poaches a top IBM exec

Posted by in categories: business, computing, economics, finance, information science, quantum physics

Editor’s note: Geoff Woollacott is Senior Strategy Consultant and Principal Analyst at Technology Business Research. IBM and NC State are coperating on quantum computing development.

HAMPTON, N.H. – JPMorgan Chase announced on Jan. 22 the hiring of Marco Pistoia from IBM. A 24-year IBM employee with numerous patents to his credit, Pistoia most recently led an IBM team responsible for quantum computing algorithms. Algorithm development will be key to developing soundly engineered quantum computing systems that can deliver the business outcomes enterprises seek at a faster and more accurate pace than current classical computing systems.

A senior hire into a flagship enterprise in the financial services industry is the proverbial canary in the coal mine, as TBR believes such actions suggest our prediction of quantum achieving economic advantage by 2021 remains on target. Quantum executives discuss the three pillars of quantum commercialization as being:
