We investigate the quantum Hall (QH) states near the charge-neutral Dirac point of a high mobility graphene sample in high magnetic fields.

We present an experimental study of four-terminal resistance fluctuations of mesoscopic samples in the quantum Hall regime.

In this paper we have showed that the qubit can be expressed through the coherent states. Consequently, a message, i.e. a sequence of qubits, is expressed as a tensor product of coherent states.

We develop quantum-optical input-output theory for resonators with arbitrary coupling strength, and for input fields whose spectrum can be wider than the cavity free-spectral range, while ensuring

The quantum lifetime of two-dimensional holes in a GaAs/AlGaAs double quantum well is determined via tunneling spectroscopy.

Abstract: We connect the quantum limits for receiver sensitivity to the Shannon channel capacity and identify the corresponding quantum limits for direct-detection on-off keying modulation with for

Abstract—The search for schemes that minimize the energy associated with the transmission of information is a longstanding fundamental issue in communication theory.

The ground state of a 2D electron system for Landau level filling factor V->0 is a Wigner solid whereas for finite filling-factors the quantum liquids of the FQHE prevail.

The Casimir force is the attraction between uncharged metallic surfaces as a result of quantum mechanical vacuum fluctuations of the electromagnetic field.

We construct arbitrary matrix elements of the quantum evolution operator for a wide class of self-adjoint canonical Hamiltonians, including those which are polynomial in the Heisenberg operators, a
