Effects of underlying topology on quantum state discrimination
In this work, we show that quantum state discrimination can be modified due to a change in the underlying topology of a system. In particular, we...

11 Discrimination of Quantum States
The problem of discriminating among given nonorthogonal quantum states is underlying many of the schemes that have been suggested for quantum...

General measurements with limited resources and their application to quantum unambiguous state discrimination
In this report, we present a framework for implementing an arbitrary n -outcome generalized quantum measurement (POVM) on an m -qubit register as a...

Relations Between State Discrimination and State Exclusion
Consider a quantum system prepared in a state chosen from a known set, the aim of quantum state discrimination is to perform a measurement on the...

12 Quantum States: Discrimination and Classical Information Transmission.A Review of Experimental Progress
The purpose of this chapter is to review the experimental achievements made to date in two closely related areas of quantum information science....

Effective quantum channel for minimum error discrimination
In this study, we consider a quantum channel that may help to discriminate quantum states, by which we may provide the solution for the unsolved...

Quantum algorithm for quantum state discrimination via partial negation and weak measurement
The quantum state discrimination problem is to distinguish between non-orthogonal quantum states. This problem has many applications in quantum...

Demonstration of \(\mathcal{P}\mathcal{T}\)-symmetric quantum state discrimination
The fundamental quantum mechanical features forbid non-orthogonal quantum states to be distinguished accurately through a single-shot measurement....

Deterministic Bell state measurement with a single quantum memory
Entanglements serve as a resource for any quantum information system and are deterministically generated or swapped by a joint measurement called...

Short-distance quantum state preparation of an arbitrary two-qubit state via GHZ state
Fusing the idea of short-distance teleportation and remote quantum state preparation (QSP), we first propose a novel deterministic QSP scheme to...

Discrimination of Quantum States Under Locality Constraints in the Many-Copy Setting
We study quantum hypothesis testing between orthogonal states under restricted local measurements in the many-copy scenario. For testing arbitrary...

Configurable circular-polarization-dependent optoelectronic silent state for ultrahigh light ellipticity discrimination
Filterless light-ellipticity-sensitive optoelectronic response generally has low discrimination, thus severely hindering the development of...

Complete and fidelity-robust hyperentangled-state analysis of photon systems with single-sided quantum-dot-cavity systems under the balance condition
Hyperentangled Bell-state analysis (HBSA) for two-photon systems and hyperentangled Greenberger–Horne–Zeilinger-state analysis (HGSA) for...

3 Maximum-Likelihood Methodsin Quantum Mechanics
Maximum Likelihood estimation is a versatile tool covering wide range of applications, but its benefits are apparent particularly in the quantum...

Steady-state quantum steering in a largely detuned optomechanical cavity
We investigate quantum steering and quantum entanglement in a hybrid cavity optomechanical system. The system model consists of an optical cavity, a...

Quantum disordered ground state in the triangular-lattice magnet NaRuO2
It has long been hoped that spin liquid states might be observed in materials that realize the triangular-lattice Hubbard model. However, weak...

Optimality and Complexity in Measured Quantum-State Stochastic Processes
If an experimentalist observes a sequence of emitted quantum states via either projective or positive-operator-valued measurements, the outcomes form...

Unambiguous correct discrimination of linearly dependent states with multiple copies
In this paper, we investigate the unambiguous correct discrimination of three multi-copy quantum states with equal a priori probability. The...
