1. von Neumann Versus Shannon Entropy
... find just one of the states, q i , to which we would then assign an entropy of zero. The density matrix (3.2.5.2) does, however, account for the reduction of the wavepacket ; the irreversible, indeterminate, -process. So whatever physical interactions are involved when the apparatus measures the sys ...

Canonical Transformations in Quantum Mechanics
... This definition applies at the purely algebraic level, and no Hilbert space or inner product need be mentioned. As a consequence, the transformation is itself neither unitary nor non-unitary. The immediate implication is that quantum canonical transformations may be non-unitary, a generalization bey ...

Mutually Unbiased bases: a brief survey
... To determine a complex matrix we need to specify 2d2 real numbers. The requirement of hermiticity cuts this number by two and the unitary trace cuts one more degree of freedom. Hence to determine a density matrix we need d2 − 1 real numbers. The problem of quantum tomography is to determine the quan ...

Quantum Money from Hidden Subspaces
... These early ideas about quantum money inspired the field of quantum cryptography [13]. But strangely, the subject of quantum money itself lay dormant for more than two decades, even as interest in quantum computing exploded. However, the past few years have witnessed a “quantum money renaissance.” ...
