“…Here, as seen from (13), N is the number of successive scatterings carried out on the quantum memory. (8) The quantum memory as discussed here has implications for a number of topics. For example, in the context of quantum cryptography, it may be used as a device for eavesdropping on quantum key distribution (QKD).…”

An essential component of any quantum computer is the quantum memory, the content of which is a pure quantum state. A program to study the quantum memory is initiated here, where the spatial variables are of central importance. The presence of the spatial variables makes it possible to apply the powerful and welldeveloped theory of scattering: The fundamental operations of writing on, reading and resetting the quantum memory are all performed through scattering from the memory. The requirement that the quantum memory must remain in a pure state after scattering implies that the scattering is of a special type, and only certain incident waves are admissible. Models based on the coupled-channel Schrödinger equation for potential scattering are formulated, where there is indeed the required large collection of admissible incident waves. On the basis of these models, certain types of decoherence are unavoidable. Such decoherence and the necessity of using the relativistic Schrödinger equation are discussed. One of the implications of quantum memory is the possible lack of security for the quantum key distribution in quantum cryptography.

“…It may be noted that while time reversal is not an invariance of nature, its violation involves the second and third generations of quarks, [8][9][10][11] which are not expected to play any significant role in quantum memory.…”

“…As Dr. Roberts has explained, what the Cronin-Fitch experiment (Christenson, Cronin, Fitch, & Turlay, 1964) establishes directly is that the weak interactions are not invariant under CP, i.e., under the simultaneous operations of charge conjugation C and reflection through a mirror, P. As normally formulated, the parity operation is meaningful only if the underlying space-time is flat, i.e., represented by Minkowski space-time. This means that one ignores curvature and therefore gravity.…”

“…It is the first discovery of the CP violation in meson decays other than in neutral K-meson decays 3) and it proved that the CP violation in meson decays can be explained by the theory formulated by Makoto Kobayashi and Toshihide Maskawa in 1973. 4) In this article, we present how the B-factory project started at KEK and how the discovery of CP violation in B-meson decay was made.…”
