T-NiSQ

T-NiSQ Tensor Networks in Simulation of Quantum matter In the Quantum Science era where Noisy Intermediate-Scale Quantum (NISQ) devices are accessible, quantum information tools to guide their development play a fundamental role. With the foreseen increasing complexity of available NISQ devices, their classical simulations – that drove their development until now – will soon fail to…

SuperLink

SuperLink Superconducting quantum-classical linked computing systems SuperLink aims at tackling critical open problems in quantum computing with superconducting qubits. Superconducting qubits are leading candidates for scaling to disruptively useful quantum computations. However, it has become clear that scaling beyond 100 qubits will require dramatically different architectures since the scientific and engineering overheads of control and…

SPARQL

SPARQL Sequential parametric amplification: quantum technology with multimode light Squeezing is a valuable quantum resource, which enables sensitive optical measurements by overcoming the shot noise – the noise stemming from the photon structure of light. At the same time, squeezing is susceptible to optical loss and inefficient detection, which limits its use in technology. SPARQL…
