A 3-mode optomechanical system (e.g., with two electromagnetic fields coupled to a single mode of a mechanical resonator) is a key element of hybrid quantum systems. [more]

A new frontier of extreme light at Exawatt level is discussed. This frontier has approached to us much closer than we thought till only recently. [more]

“We propose to use Quantum Hall edge channels in order to generate long-range entanglement between spatially separated spin qubits. Since the entanglement is actively stabilized by purely dissipative dynamics, our scheme is inherently robust against noise and imperfections.” [more]

The active laser cavity can be considerably more sensitive than a passive one to minute perturbations. The difference in sensitivity between passive and active resonator sensors is akin to forensic dissection as compared to vivisection. [more]

Quantum correlations are strongly enhanced near quantum critical points, which opens attractive prospects for applications such as quantum-enhanced metrology. [more]
