A team of researchers at Los Alamos National Laboratory and Google has reviewed the state of the art of Variational Quantum Algorithms (VQAs). Applications such as simulating large quantum systems or solving large-scale linear algebra
Despite the fundamental importance of quantum entanglement in many-body systems, our understanding is mostly limited to bipartite situations. Indeed, even defining appropriate notions of multipartite entanglement is a significant challenge for general quantum systems. This
A team of scientists at Freie Universität Berlin has developed an artificial intelligence (AI) method for calculating the ground state of the Schrödinger equation in quantum chemistry. Up to now, it has been impossible to
In the effort to develop disruptive quantum technologies, germanium is emerging as a versatile material to realize devices capable of encoding, processing and transmitting quantum information. These devices leverage the special properties of holes in
A technique created by researchers at University of Pittsburgh enables them to “sketch” patterns of electrons into a programmable quantum material (Lanthanum Aluminate/Strontium Titanate or “LAO/STO”). Using this approach, they can create quantum devices and
Paulina Mazurek, CEO of Polish quantum startup BEIT, is the first nominee of the ‘Quantum Personality of the Year 2020‘ and she definitely deserves that honour. First, because she has co-founded her company in 2016, when a

Powerful quantum computers could be built by linking together multiple superconducting quantum processors. Promising schemes involve exchanging visible or infrared photons through optical fibers and converting such photons into microwave photons that can couple to
Researchers at Stevens Institute of Technology have created a chip-based photon source 100 times more efficient than previously possible. To create photon pairs, researchers trap light in carefully sculpted nanoscale microcavities; as light circulates in
Scientists from EPFL, MIT, and CEA Saclay demonstrate a state of vibration that exists simultaneously at two different times. They evidence this quantum superposition by measuring the strongest class of quantum correlations between light beams
ETH Zurich announced its new Quantum Center. The center has 28 founding members from 6 different departments of ETH Zurich and the Paul Scherrer Institute. The purpose of the new ETH Quantum Center is to ensure
