Skoltech Scientist Bridges the Gap Between Quantum Simulators and Quantum Computers

A researcher from Skoltech has filled in the gaps connecting quantum simulators with more traditional quantum computers, discovering a new computationally universal model of quantum computation, the variational model. The paper was published as a Letter in the journal Physical Review A. The work made the Editors’ Suggestion list.

Research Solves a Key Problem of Usability for Quantum Machine Learning

Many machine learning algorithms on quantum computers suffer from the dreaded "barren plateau" of unsolvability, where they run into dead ends on optimization problems. This challenge had been relatively unstudied--until now. Rigorous theoretical work has established theorems that guarantee whether a given machine learning algorithm will work as it scales up on larger computers.

Increase in Funding Allows Sweden's Quantum Computer Project to Shift Up a Gear

( Chalmers University of Technology ) Knut and Alice Wallenberg Foundation is almost doubling the annual budget of the research initiative Wallenberg Centre for Quantum Technology, based at Chalmers University of Technology, Sweden. This will allow the centre to shift up a gear and set even higher goals - especially in its development of a quantum computer. Two international workshops will kick-start this new phase.

Using Tailored Light Pulses to Individually Address Quantum Emitters

In order to exploit the properties of quantum physics technologically, quantum objects and their interaction must be precisely controlled. In many cases, this is done using light. Researchers at the University of Innsbruck and the Institute of Quantum Optics and Quantum Information (IQOQI) of the Austrian Academy of Sciences have now developed a method to individually address quantum emitters using tailored light pulses.
