Probability Representation of Quantum States
Entropy, 2021 The review of new formulation of conventional quantum mechanics where the quantum states are identified with probability distributions is presented. The invertible map of density operators and wave functions onto the probability distributions describing ...

Invariance of separability probability over reduced states in 4x4 bipartite systems [PDF]
, 2017 The geometric separability probability of composite quantum systems is extensively studied in the last decades. One of most simple but strikingly difficult problem is to compute the separability probability of qubit-qubit and rebit-rebit quantum states ...

A Pair of Coupled Waveguides as a Classical Analogue for a Solid-State Qubit
Sensors, 2022 We have determined conditions when a pair of coupled waveguides, a common element for integrated room-temperature photonics, can act as a qubit based on a system with a double-well potential.

A single photon produces general W state of N qubits and its application [PDF]
, 2007 Based on the Wu's scheme[1], We prepare the general N-qubit W state. We find that the concurrence of two qubits in general N-qubit W state is only related to their coefficients and we successfully apply the general N-qubit W state to quantum state ...

Conference on Lasers and Electro-Optics, 2019 AbstractFree‐electron interactions with laser‐driven nearfields can quantize the electrons’ energy spectrum and provide control over this quantized degree of freedom. The study proposes to use such interactions to promote free electrons as carriers of quantum information and show how to create a qubit on a free electron, which holds promise for ...

Macroscopic Many-Qubit Interactions in Superconducting Flux Qubits [PDF]
, 2007 Superconducting flux qubits are considered to investigate macroscopic many-qubit interactions. Many-qubit states based on current states can be manipulated through the current-phase relation in each superconducting loop.

Quantum Logic Locking for Security
J, 2023 Having access to a unique quantum circuit that one wants to protect against use by others is a very likely scenario in industrial computing. However, currently, users rely on classical computer security schemes, which have known shortcomings.
