Increase Reliability of Quantum Computers

Authors: George Rajna

A new technique by researchers at Princeton University, University of Chicago and IBM significantly improves the reliability of quantum computers by harnessing data about the noisiness of operations on real hardware. [33] A world-record result in reducing errors in semiconductor 'spin qubits', a type of building block for quantum computers, has been achieved using the theoretical work of quantum physicists at the University of Sydney Nano Institute and School of Physics. [32] Quantum communication, which ensures absolute data security, is one of the most advanced branches of the "second quantum revolution". [31] Researchers at the University of Bristol's Quantum Engineering Technology Labs have demonstrated a new type of silicon chip that can help building and testing quantum computers and could find their way into your mobile phone to secure information. [30] Theoretical physicists propose to use negative interference to control heat flow in quantum devices. [29] Particle physicists are studying ways to harness the power of the quantum realm to further their research. [28] A fundamental barrier to scaling quantum computing machines is "qubit interference." In new research published in Science Advances, engineers and physicists from Rigetti Computing describe a breakthrough that can expand the size of practical quantum processors by reducing interference. [26] The search and manipulation of novel properties emerging from the quantum nature of matter could lead to next-generation electronics and quantum computers. [25]
