Superconductor modulation circuits for Qubit control at microwave frequencies

Sasan Razmkhah, Ali Bozbey, Pascal Febvre

Readout and control of qubits are limiting factors in scaling quantum computers. An ideal solution is to integrate energy-efficient cryogenic circuits close to the qubits to perfor…

Group-covariant extreme and quasi-extreme channels

Laleh Memarzadeh, Barry C. Sanders

Constructing all extreme instances of the set of completely positive trace-preserving (CPTP) maps, i.e., quantum channels, is a challenging valuable open problem in quantum informa…

On detection statistics in double-double-slit experiment

MohammadJavad Kazemi, Vahid Hosseinzadeh

In this paper, we analyze the statistics of detection data in a general double-double-slit experiment. The two particles are detected at random times which are not equal in general…

Capacities of the covariant Pauli channel

Abbas Poshtvan, Vahid Karimipour

We study the four well-known capacities of a two-parameter family of qubit Pauli channels. These are the channels which are covariant under the SO(2) group and contain the depolari…

Continuous quantum clock with high precision and long recurrence time

Mehdi Ramezani, Morteza Nikaeen, Alireza Bahrampour

Continuous clocks, i.e. the clocks that measure time in a continuous manner, are regarded as an essential component of sensing technology. Precision and recurrence time are two bas…

Accessible maps in a group of classical or quantum channels

Koorosh Sadri, Fereshte Shahbeigi, Zbigniew Puchała +1

We study the problem of accessibility in a set of classical and quantum channels admitting a group structure. Group properties of the set of channels, and the structure of the clos…

Irreversible Entropy Production rate in a parametrically driven-dissipative System: The Role of Self-Correlation between Noncommuting Observables

Sareh Shahidani, Morteza Rafiee

In this paper, we explore the emergence of the Wigner entropy production rate in the stationary state of a two-mode Gaussian system. The interacting modes dissipate into different…

Discrimination of dephasing channels

Milajiguli Rexiti, Laleh Memarzadeh, Stefano Mancini

The problem of dephasing channel discrimination is addressed for finite-dimensional systems. In particular, the optimization with respect to input states without energy constraint…
