Researchers at Toshiba Corporation have achieved a breakthrough in quantum computer architecture: the basic design for a double-transmon coupler that will improve the speed and accuracy of quantum computation in tunable couplers. ...
A research partnership at the Advanced Quantum Testbed (AQT) at Lawrence Berkeley National Laboratory (Berkeley Lab) and Chicago-based Super.tech (acquired by ColdQuanta in May 2022) demonstrated how to optimize the execution ...
Quantum computers, devices that exploit quantum phenomena to perform computations, could eventually help tackle complex computational problems faster and more efficiently than classical computers. These devices are commonly ...
Research conducted within the Cluster of Excellence "Matter and Light for Quantum Computing" (ML4Q) has analyzed cutting-edge device structures of quantum computers to demonstrate that some of them are indeed operating dangerously ...
In a new report now published in Science Advances, Peter A. Spring and a team of scientists in physics at the Oxford University described qubit coherence and low cross-talk and single-qubit gate errors in superconducting ...
For quantum computers to surpass their classical counterparts in speed and capacity, their qubits—which are superconducting circuits that can exist in an infinite combination of binary states—need to be on the same wavelength. ...
The connection between microscopic material properties and qubit coherence are not well understood despite practical evidence that material imperfections present an obstacle to applications of superconducting qubits. In a ...
Russian scientists have experimentally proved the existence of a new type of quasiparticle—previously unknown excitations of coupled pairs of photons in qubit chains. This discovery could be a step towards disorder-robust ...
Scientists believe that individual light particles, or photons, are ideally suited for sending quantum information. Encoded with quantum data, they could literally transfer information at the speed of light. However, while ...
The secret to building superconducting quantum computers with massive processing power may be an ordinary telecommunications technology—optical fiber.
