The promise of two-dimensional electron gases in quantum wells for wide-ranging quantum devices
Two-dimensional electron gases in quantum wells are a powerful resource for several quantum technology applications, including quantum sensing, metrology, and topological quantum computing. In a conventional quantum computer, information is localized within a single particle (or qubit). Noise that affects that qubit can cause quantum information to get scrambled and lost. For fault-tolerant quantum […]

Building Blocks for Quantum Neuromorphic Computing: Superconducting Quantum Memcapacitors
Quantum neuromorphic computing (QNC) is a novel method that combines quantum computing with brain-inspired neuromorphic computing. Neuromorphic computing performs computations using a complex ensemble of artificial neurons and synapses (i.e., electrical circuits) to emulate the human brain. QNC may lead to a quantum advantage by realizing these components with quantum memory elements, or memelements, which […]

Professor David Hawthorn’s lab uses x-rays to see waves of electrons in superconductors
Monday, November 13, 2020 Although physicists understand the properties of metals, insulators and semiconductors extremely well, the basic physics of high-temperature superconductors has remained a great mystery for over 30 years. A new study using cutting edge experimental techniques by University of Waterloo researchers has now shed some light on the properties of one class […]

Quantum researchers able to split one photon into three
Thursday, February 27, 2020 En français Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo report the first occurrence of directly splitting one photon into three. The occurrence, the first of its kind, used the spontaneous parametric down-conversion method (SPDC) in quantum optics and created what quantum optics researchers call […]

Composite Superconductors for Improved Quantum Coherence
Summary Conventional superconductors have trouble performing well in magnetic fields required for electron spin resonance (ESR) – based quantum information processing applications. We can, however, use proximity engineering to select desired properties from different materials and combine them for improved superconducting performance in magnetic fields — an improvement that would have strong implications for […]
