Sourcing semiclassical gravity from spontaneously localized
... this does not discredit it a priori in the eventuality that space-time is fundamentally classical. However, and as natural as it may seem, the latter standard semiclassical approach is plagued by foundational problems. The most obvious one is that such a semiclassical coupling means nonlinear determ ...

Precedence and freedom in quantum physics
... An entangled state can be novel in that it can be formed from a composition of subsystems into a state never before occurring in the prior history of the universe. This is common for example in biology where natural selection can give rise to novel proteins and sequences of nucleic acids which almos ...

INTRODUCTION TO QUANTUM FIELD THEORY OF POLARIZED
... It is conceptually convenient for the quantization procedure to represent the electromagnetic field as a sum over discrete modes as we did in Eq. (7.20). For practical calculations of physical quantities we however need to use continuous functions and replace the mode sums by integrals over frequenc ...

Factoring 51 and 85 with 8 qubits
... Given the considerable interest in experimental demonstrations of Shor’s algorithm, it is reasonable to ask what constitutes a ‘‘genuine’’ demonstration of this important algorithm, and whether the cases presented here should be considered as such. In our opinion a genuine implementation should use ...

A Post Processing Method for Quantum Prime Factorization
... B. In a classic computer the smallest unit for saving data is a bit but at Quantum physics the smallest unit for saving data is a qubit then I have to simulate qubit by a class named Qubit. Qubit variable includes two basic states |0> (zero state) and |1> (one state) which with a probability like α2 ...
