Photons at microwave and optical frequencies are principal carriers for quantum information.
While microwave photons can be effectively controlled at the local circuit level, optical …

We construct a new class of quantum error-correcting codes for a bosonic mode, which are
advantageous for applications in quantum memories, communication, and scalable …

Solid-state microwave systems offer strong interactions for fast quantum logic and sensing
but photons at telecom wavelength are the ideal choice for high-density low-loss quantum …

The Wigner function was formulated in 1932 by Eugene Paul Wigner, at a time when
quantum mechanics was in its infancy. In doing so, he brought phase space representations …

Nonreciprocal microwave devices are ubiquitous in radar and radio communication and
indispensable in the readout chains of superconducting quantum circuits. Since they …

Linking classical microwave electrical circuits to the optical telecommunication band is at the
core of modern communication. Future quantum information networks will require coherent …

Nonreciprocal circuit elements form an integral part of modern measurement and
communication systems. Mathematically they require breaking of time-reversal symmetry …

Large-scale quantum information processing networks will most probably require the
entanglement of distant systems that do not interact directly. This can be done by performing …

The faithful storage and coherent manipulation of quantum states with matter-systems would
enable the realization of large-scale quantum networks based on quantum repeaters. To …
