Random numbers are increasingly important to our digitally connected world, with applications that include e-commerce, cryptography, and cloud computing. Producing a large amount of truly random numbers quickly, though, is a challenge.

To speed things up, a team of researchers has developed a compact laser that can produce these random numbers 100 times quicker than the fastest current systems. The results are published February 26 in the journal Science.

Yale researchers working with scientists at the U.S. Department of Energy’s Brookhaven National Laboratory have demonstrated the ability to control spin dynamics in magnetic materials by altering the materials’ thickness. The research stands as a major achievement in the emerging field of spintronics — the manipulation of electron spin — and could prove useful in developing the next generation of electronics.

Yale physicists have developed an error-correcting cat — a new device that combines the Schrödinger’s cat concept of superposition (a physical system existing in two states at once) with the ability to fix some of the trickiest errors in a quantum computation.

It is Yale’s latest breakthrough in the effort to master and manipulate the physics necessary for a useful quantum computer: correcting the stream of errors that crop up among fragile bits of quantum information, called qubits, while performing a task.

A research result by Yale physicists lends credibility to an exotic proposal for safeguarding quantum information called topological quantum protection. A team led by Michel Devoret, the F.W. Beinecke Professor of Applied Physics and Physics, has applied the tools of circuit quantum electrodynamics to achieve the continuous monitoring of a quasiparticle’s spin.

Enshrined by the laws of Austrian physicists Josef Stefan and Ludwig Boltzmann in the late 19th Century, scientists have long understood the general principles of heat-energy transfer between the sun and planet Earth.

But at much closer separations, where photons can effectively “tunnel” between two bodies, the maximum rate and size at which two objects – one hot, one cold – can transfer heat has remained unknown.

Yale scientists have discovered that laser light can be used to cool traveling sound waves in a silicon chip. Their findings appear in the Nov. 27 online edition of the journal Physical Review X.

Most scientists will never have the opportunity to travel to the South Pole for their research, but then again, most scientists aren’t Faustin Carter (PhD ’15). Carter works as a postdoctoral researcher at Argonne National Laboratory in the High Energy Physics division. He is part of a group that specializes in building detectors for esoteric applications. The group’s primary focus over the last several years has been building and testing detectors for a massive upgrade to a telescope located at the geographic South Pole in Antarctica.

Dan Prober received the IEEE Council on Superconductivity award for 2018.
The award given in recognition of  his continuing and significant contributions in the field of superconductive electronics, in particular:

As a Yale undergraduate, Peter Schiffer ’88 admits he spent more time at the Yale Political Union (YPU) than in the lab. It’s rather ironic that, nearly three decades later, the Piersonite and Progressive Party member has returned to Yale as vice provost for research, a role “intended to support research and scholarship across the entire enterprise and not just science and engineering — the social sciences, the humanities, and the arts.” Read more

Yale scientists Hui Cao, Peter Raymond, and Karen Seto have been named by their peers as fellows of the American Association for the Advancement of Science (AAAS).

They will be among 396 members elevated to the rank of fellow at the Feb. 17 AAAS annual meeting in Austin, Texas. Each honoree will be presented with an official certificate and a gold and blue rosette pin.

Yale scientists have created a simple-to-produce device that uses sound waves to store quantum information and convert it from one form to another, all inside a single, integrated chip.

The device allows a superconducting artificial atom — a qubit — to exchange energy and quantum information with a high frequency bulk acoustic wave resonator (HBAR). The ability to manipulate and store fragile quantum data in a robust and easy-to-manufacture way is a crucial step in the development of quantum computing technology.

Peter Schiffer, an experimental physicist currently at the University of Illinois at Urbana Champaign, has been named the university’s inaugural vice provost for research — a post created to bring a new level of strategic attention to Yale’s science and research enterprise, announced President Peter Salovey and Provost Benjamin Polak.

In October 2016, the Yale Quantum Institute launched a Call for Art Proposals to commission quantum physics themed artwork to fill a bare wall at the entrance of the institute. A few months after the call, we received 26 proposals from Yale Students and New Haven based artists. The proposals were all of great quality and we were very impressed by the connection these artists have made with quantum physics, a fairly hard to access subject.

Professor Michel Devoret has received the 2016 Olli V. Lounasmaa Memorial Prize for his pioneering investigations and applications of macroscopic quantum phenomena at low temperatures. The prize was announced on August 16th 2016 at the international Quantum Fluids and Solids Conference (QFS2016) in Praque, Czech Republic.

Yale Researchers have crossed the “break even” point in preserving a bit of quantum information for longer than the lifetime of its constituent parts, as published in Nature.

A novel system has been created to encode, spot errors, decode, and correct errors in a quantum bit, also known as a “qubit.” The development of such a robust method of Quantum Error Correction (QEC) has been one of the biggest remaining hurdles in quantum computation.
