Driven by the rapid progress in quantum hardware, recent years have witnessed a furious
race for quantum technologies in both academia and industry. Universal quantum …

The power of quantum computing technologies is based on the fundamentals of quantum
mechanics, such as quantum superposition, quantum entanglement, or the no-cloning …

Linear optics with photon counting is a prominent candidate for practical quantum
computing. The protocol by Knill, Laflamme, and Milburn [2001, Nature (London) 409, 46] …

In 2001, all-optical quantum computing became feasible with the discovery that scalable
quantum computing is possible using only single-photon sources, linear optical elements …

We investigate phonon induced electronic dynamics in the ground and excited states of the
negatively charged silicon-vacancy (${\rm Si}{{{\rm V}}^{-}} $) centre in diamond. Optical …

Quantum computation and communication exploit the quantum properties of superposition
and entanglement in order to perform tasks that may be impossible using classical means. In …

Quantum networks build on entanglement and quantum measurement to achieve tasks that
are beyond the reach of classical systems. Using quantum effects, we can detect the …

We describe and analyze an efficient register-based hybrid quantum computation scheme.
Our scheme is based on a probabilistic, heralded optical connection among local five-qubit …

We introduce an adaptable and modular hybrid architecture designed for fault-tolerant
quantum computing. It combines quantum emitters and linear-optical entangling gates to …

Quantum error correction holds the key to scaling up quantum computers. Cosmic ray events
severely impact the operation of a quantum computer by causing chip-level catastrophic …
