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.
Researchers have recently displayed the interaction of superconducting qubits; the basic unit of quantum information, with surface acoustic wave resonators; a surface-wave equivalent of the crystal resonator, in quantum physics. ...
A new computer program that spots when information in a quantum computer is escaping to unwanted states will give users of this promising technology the ability to check its reliability without any technical knowledge for ...
An international team of physicists at ETH Zurich, Aalto University, the Moscow Institute of Â鶹ÒùÔºics and Technology, and the Landau Institute for Theoretical Â鶹ÒùÔºics in Moscow has demonstrated that algorithms and hardware ...
Simulation of quantum chemistry is one of the killer applications of quantum computers. In recent years, Google, IBM and other IT companies have been engineering increasingly good superconducting qubits for the purpose of ...
Builders of future superconducting quantum computers could learn a thing or two from semiconductors, according to a report in Nature Communications this week. By leveraging the good ideas of the natural world and the semiconductor ...
