The figure pictures the simplest example of parity games. Alice (A) flicks a certain number of marbles towards Bob (B), with the aim of learning whether the number of twisted tubes is even or odd. The players need four ordinary classical marbles to complete the task. In contrast, already two quantum marbles would suffice. Credit: © Borivoje Dakić

Playing games with quantum interference

One of the most striking features of quantum mechanics is the superposition principle. This principle can be most easily illustrated via the double-slit experiment, which involves a particle that is sent through a plate pierced […]

Robots learn faster with Quantum Technology

An experiment at the University of Vienna has showed that quantum technology enables a speed-up in the machine learning using a quantum processor for single photons as a robot. The team has made use of […]

Qblox unveils next-generation RF Quantum control stacks

Yesterday, Quantum Computer scientists needed to integrate numerous hardware technologies to control and readout qubits effectively. Qblox, a Dutch startup, has just launched their Radio Frequency (RF) line consisting of fully-integrated quantum control stacks providing […]

The hunt for the Quantum collapse

Leiden University physicists simulated an experiment to catch this mysterious moment of superposition collapsing for the Schrödinger’s cat. The Leiden physicists decided to open the hunt for the collapse from the perspective of an amplifier […]

Powerful spintronic magnet paired with Graphene

An international research team led by the University at Buffalo has described how they paired a magnet with graphene, and induced what they describe as “artificial magnetic texture” in the nonmagnetic wonder material. For their experiments, researchers […]

Beams of entangled atoms

Beams of entangled atoms

A new method has been developed at TU Wien, Austria, to produce entangled atom pairs and not just atoms which are emitted in all directions, but well-defined beams. This was achieved with the help of ultracold atom clouds in electromagnetic traps.

Performance advantage in quantum simulation

Performance advantage in quantum simulation

D-Wave Systems has published a milestone study in collaboration with scientists at Google, demonstrating a computational performance advantage, increasing with both simulation size and problem hardness, to over 3 million times that of corresponding classical methods.

Quantum or Classical Gravity?

Quantum or Classical Gravity?

An international team led by the University of Nottingham, has demonstrated that only quantum and not classical gravity could be used to create a certain informatic ingredient that is needed for quantum computation.

Unique Majorana particles found in a magnetic material

For years, physicists have been looking for materials that emulate a Kitaev honeycomb (solid-state model known to birth Majorana fermions in magnetic fields). Physicists from Chung-Ang University, Korea, unveiled the existence of Majorana fermions in α-RuCl3, […]
