Quantum-mechanical effects at the macroscopic level were first explored in Josephson-
junction-based superconducting circuits in the 1980s. In recent decades, the emergence of …

Engineered quantum systems enabling novel capabilities for computation and sensing have
blossomed in the last decade. Architectures benefiting from combining complementary …

We propose an experimentally feasible method for enhancing the atom-field coupling as
well as the ratio between this coupling and dissipation (ie, cooperativity) in an optical cavity …

We show how to create quantum squeezed states of magnons and phonons in a cavity
magnomechanical system. The magnons are embodied by a collective motion of a large …

We show how to implement stationary one-way quantum steering with strong entanglement
in a cavity magnonic system that consists of two magnon modes and a microwave cavity …

While a propagating state of light can be generated with arbitrary squeezing by pum** a
parametric resonator, the intraresonator state is limited to 3 dB of squeezing. Here, we …

Recently gained insights into equilibrium squeezing and entanglement harbored by
magnets point toward exciting opportunities for quantum science and technology, while …

As a genuine many-body entanglement, spin squeezing (SS) can be used to realize the
highly precise measurement beyond the limit constrained by classical physics. Its generation …

We demonstrate a scheme for the generation of bipartite and tripartite entanglement, as well
as he implementation of stable and controllable long-distance one-way and asymmetric two …

Microwave squeezing represents the ultimate sensitivity frontier for superconducting qubit
measurement. However, measurement enhancement has remained elusive, in part because …
