Qubits as Parafermions [PDF]

open access: yes, 2001
Qubits are neither fermions nor bosons. A Fock space description of qubits leads to a mapping from qubits to parafermions: particles with a hybrid boson-fermion quantum statistics.

Decoherence and dephasing in coupled Josephson-junction qubits

open access: yes, 2001
We investigate the decoherence and dephasing of two coupled Josephson qubits. With the interaction between the qubits being generated by current-current correlations, two different situations in which the qubits are coupled to the same bath, or to two ...

Metastable Superconducting Qubit [PDF]

open access: yesPhysical Review Letters, 2010
We propose a superconducting qubit design, based on a tunable RF-SQUID and nanowire kinetic inductors, which has a dramatically reduced transverse electromagnetic coupling to its environment, so that its excited state should be metastable. If electromagnetic interactions are in fact responsible for the current excited-state decay rates of ...

Getting through to a qubit by magnetic solitons

open access: yesNew Journal of Physics, 2015
We propose a method for acting on the spin state of a spin- $\frac{1}{2}$ localized particle, or qubit , by means of a magnetic signal effectively generated by the nearby transit of a magnetic soliton, there conveyed through a transmission line. We first

Real-Time Threat Mitigation in Financial IT Infrastructures Using Quantum Computing [PDF]

open access: yesInternational Journal of Electronics and Telecommunications
Financial institutions continue to face evolving cyber security threats that require immediate detection and mitigation to prevent significant damage. Classical-based cyber security mechanisms struggle to keep up with these emerging threats due to their ...

Kagome qubit ice

open access: yesNature Communications, 2023
AbstractTopological phases of spin liquids with constrained disorder can host a kinetics of fractionalized excitations. However, spin-liquid phases with distinct kinetic regimes have proven difficult to observe experimentally. Here we present a realization of kagome spin ice in the superconducting qubits of a quantum annealer, and use it to demonstrate

Optimally preserving quantum correlations and coherence with eternally non-Markovian dynamics

open access: yesNew Journal of Physics, 2022
We demonstrate, both analytically and experimentally, the usefulness of non-Markovianity for preserving correlations and coherence in quantum systems.

The n-tangle of odd n qubits

open access: yes, 2011
Coffman, Kundu and Wootters presented the 3-tangle of three qubits in [Phys. Rev. A 61, 052306 (2000)]. Wong and Christensen extended the 3-tangle to even number of qubits, known as $n$-tangle [Phys. Rev. A 63, 044301 (2001)]. In this paper, we propose a
