DISCRETE COHERENT STATES FOR n QUBITS
KTH, School of Information and Communication Technology (ICT), Optics and Photonics, Quantum Electronics and Quantum Optics, QEO.ORCID iD: 0000-0002-2082-9583

Abstract [en]

Discrete coherent states for a system of n qubits are introduced in terms of eigenstates of the finite Fourier transform. The properties of these states are pictured in phase space by resorting to the discrete Wigner function.
