New quantum computer design to predict molecule properties
The standard approach to build a quantum computer with Majoranas as building blocks is to convert them into qubits. However, a promising application of quantum computing—quantum chemistry—would require these qubits to be converted again into so-called fermions. Physicists from Leiden and Delft suggest…

A new building block for the quantum computer
The race to build the first quantum computer is still ongoing, but Morten Bakker has made big step forward in that process with qubits. A qubit is a unit of quantum information that can be produced in large numbers on chips. Qubits capable of exchanging photons (light particles) could be used in the…

Magnetic imaging of spin waves and magnetic phase transitions with nitrogen-vacancy centers in diamond
The elementary excitations of magnets are called spin waves, and their corresponding quasi-particles are known as magnons. The rapidly growing field of Magnonics aims at using them as information carriers in a new generation of electronic devices, (almost) free of electric currents.

Consortium puts Quantum Computer in the cloud
The quantum computer is on its way, but is society ready for it? Quantum computers have a reputation of being difficult to grasp because of their complexity. This limits society’s ability to envision future applications creating a gap between society and quantum computers. A consortium of 14 knowledge…

Black holes with ‘dreadlocks’ offer insight into quantum matter
Physicists understand little about quantum matter, which is a building block of future quantum computers. Theorists have now discovered that black holes with ‘dreadlocks’ harbor a similarly exotic order pattern, which makes calculations on quantum matter easier. Publication in Physical Review Letter…

How quantum mechanics threatens our digital lives – and makes them safer
Much of the work of Serge Fehr, Professor of Quantum Information Theory, is abstract and theoretical and comprehensible to very few people. But his work helps make the digital world safer so that in future our internet banking will still be problem free, for instance. He will explain more in his inaugural…

Important Effect Observed in Development of Quantum Storage
Rare-earth materials are prime candidates for storing quantum information, because the undesirable interaction with their environment is extremely weak. Consequently however, this lack of interaction implies a very small response to light, making it hard to read and write data. Leiden physicists have…
