Quantum Trajectories and Quantum Measurement Theory [PDF]
Quantum and Semiclassical Optics: Journal of the European Optical Society Part B, 2003 Beyond their use as numerical tools, quantum trajectories can be ascribed a degree of reality in terms of quantum measurement theory. In fact, they arise naturally from considering continuous observation of a damped quantum system.

Quantum algorithmic measurement [PDF]
Nature Communications, 2022 AbstractThere has been recent promising experimental and theoretical evidence that quantum computational tools might enhance the precision and efficiency of physical experiments. However, a systematic treatment and comprehensive framework are missing.

Dense Quantum Measurement Theory. [PDF]
Sci Rep, 2019 AbstractQuantum measurement is a fundamental cornerstone of experimental quantum computations. The main issues in current quantum measurement strategies are the high number of measurement rounds to determine a global optimal measurement output and the low success probability of finding a global optimal measurement output.

Quantum strategies of quantum measurements [PDF]
Physics Letters A, 2001 In classical Monty Hall problem, one player can always win with probability 2/3. We generalize the problem to the quantum domain and show that a fair two-party zero-sum game can be carried out if the other player is permitted to adopt quantum measurement strategy.

Quantum Invariant Measures [PDF]
Communications in Mathematical Physics, 2001 We derive an explicit expression for the Haar integral on the quantized algebra of regular functions C_q[K] on the compact real form K of an arbitrary simply connected complex simple algebraic group G. This is done in terms of the irreducible *-representations of the Hopf *-algebra C_q[K]. Quantum analogs of the measures on the symplectic leaves of the

Universal Quantum Measurements [PDF]
Journal of Physics: Conference Series, 2015 We introduce a family of operations in quantum mechanics that one can regard as "universal quantum measurements" (UQMs). These measurements are applicable to all finite-dimensional quantum systems and entail the specification of only a minimal amount of structure.

Undoing a Quantum Measurement [PDF]
Physical Review Letters, 2013 In general, a quantum measurement yields an undetermined answer and alters the system to be consistent with the measurement result. This process maps multiple initial states into a single state and thus cannot be reversed. This has important implications in quantum information processing, where errors can be interpreted as measurements.
