Many applications require quantum processors with millions of quantum bits. Today’s prototypes merely come up with a few of these compute units. At some point, the number of signal...

With the "High-Performance Computer and Quantum Simulator hybrid" (HPCQS) project, Europe is entering a new era of hybrid quantum high-performance computing. The aim is to closely connect two quantum simulators,...

The road to quantum computing How is quantum computer development currently progressing in Germany and Europe? Researchers at the University of Konstanz led by Professor Guido Burkard report on the...

When memory qubits and photons get entangled Encrypting data in a way that ensures secure communication is an ever-growing challenge because crucial components of today’s encryption systems cannot withstand future...

Liberating Quantum Processors from Parasitic Interactions Creating perfect entanglement – a basic prerequisite for the success of quantum computers – requires full control over all qubit-qubit interactions. Until now, this...
