Encoding a qubit in logical quantum states with wave functions characterized by disjoint
support and robust energies can offer simultaneous protection against relaxation and pure …

We investigate realistic experimental conditions under which the collective Dicke model can
be implemented in the ion-cavity QED context. We show how ideal subradiance and …

We describe how an ensemble of four-level atoms in the diamond-type configuration can be
applied to create a fully controllable effective coupling between two cavity modes. The …

We propose a protocol of the long-distance atomic-state teleportation via cavity decay, which
allows for high-fidelity teleportation even with currently available optical cavities. The …

I study an optomechanical system in which the mechanical motion of a single trapped ion is
coupled to a cavity field for the realization of a strongly quantum correlated two-mode …

During the last century since its mathematically correct formulation by Heisenberg, Dirac,
Born, Schrödinger, von Neumann and others in the late 1920's, quantum mechanics has …

It is proved that a qubit encoded in excited states of a V-type quantum system cannot be
perfectly transferred to the state of the cavity field mode using a single rectangular laser …

Over the past decade, quantum circuits have been transitioning from being useful solely in
fundamental physics research to having applications in a wide variety of fields. This has …

Systems composed of a cavity and atoms, which are trapped inside this cavity, provide a
friendly environment for engineering complex non-classical states of light [1–10]. The main …
