Introduction to Quantum Fields in Curved Spacetime
... Quantum gravity remains an outstanding problem of fundamental physics. The bottom line is we don’t even know the nature of the system that should be quantized. The spacetime metric may well be just a collective description of some more basic stuff. The fact[1] that the semi-classical Einstein equati ...

This follows from the fact that the time evolution is unitary and the eigenvalues of the density operator therefore do not change with time. Clearly ...

Quantum Factorization of 143 on a Dipolar
... Hp ¼ Hpi is a summation of all the bitwise Hamiltonians. In this way, the ground state of Hp encodes the two factors that satisfy all the bitwise equations and is the answer to our factoring problem. Thus the spectrum of Hp will not scale with N but log2 N. However, Schaller and Schützhold’s scheme ...
