Research from the McKelvey School of Engineering at Washington University in St. Louis has found a missing piece in the puzzle of optical quantum computing. Jung-Tsung Shen, associate professor in the Department of Electrical & Systems Engineering, has developed a deterministic, high-fidelity two-bit quantum logic gate that takes advantage of a new form of light.
Armonk, N.Y. and Cleveland, OH, March 30, 2021: Cleveland Clinic and IBM have announced a planned 10-year partnership to establish the Discovery Accelerator, a joint Cleveland Clinic – IBM center with the mission of fundamentally advancing the pace of discovery in healthcare and life sciences through the use of high performance computing on the hybrid cloud, artificial intelligence (AI) and quantum computing technologies.
A new Department of Energy open-access quantum computing testbed is ready for the public. Scientists from Indiana University recently became the first team to begin using Sandia National Laboratories’ Quantum Scientific Computing Open User Testbed, or QSCOUT.
Quantum technologies for computers open up new concepts of preserving the privacy of input and output data of a computation. Scientists from the University of Vienna, the Singapore University of Technology and Design and the Polytechnic University of Milan have shown that optical quantum systems are not only particularly suitable for some quantum computations, but can also effectively encrypt the associated input and output data.
A team of researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) used a quantum computer to successfully simulate an aspect of particle collisions that is typically neglected in high-energy physics experiments, such as those that occur at CERN’s Large Hadron Collider.
A multi-institutional team became the first to generate accurate results from materials science simulations on a quantum computer that can be verified with neutron scattering experiments and other practical techniques.
Borrowing a page from high-energy physics and astronomy textbooks, a team of physicists and computer scientists at Berkeley Lab has successfully adapted and applied a common error-reduction technique to the field of quantum computing.
The U.S. Department of Energy Office of Science has selected Brookhaven National Laboratory to lead one of five National Quantum Information Science Research Centers. Through hardware-software co-design, the center—called the Co-design Center for Quantum Advantage—will advance quantum computing.
Building up on their last year’s breakthrough “time reversal” experiment, two researchers from the Moscow Institute of Physics and Technology and Argonne National Laboratory have published a new theoretical study in Communications Physics. While their previous paper dealt with a predefined quantum state, this time the physicists have devised a way to time-reverse the evolution of an object in an arbitrary, unknown state.
Using a quantum computer to simulate time travel, researchers have demonstrated that, in the quantum realm, there is no “butterfly effect.” In the research, information—qubits, or quantum bits—“time travel” into the simulated past.
A research team led by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has developed a technique that could lead to new electronic materials that surpass the limitations imposed by Moore’s Law.
A team of physicists at the University of Bristol has developed the first integrated photon source with the potential to deliver large-scale quantum photonics.
An ORNL team developed the XACC software framework to help researchers harness the potential power of quantum processing units, or QPUs. XACC offloads portions of quantum-classical computing workloads from the host CPU to an attached quantum accelerator, which calculates results and sends them back to the original system.
Berkeley Lab scientists tap into graphene’s hidden talent as an electrically tunable superconductor, insulator, and magnetic device for the advancement of quantum information science
