As an atom is made to pass through the cavity, a microwave pulse switched in the first Ramsey zone R1 causes a transition to a specified basic qubit state, following which an entangled state of the atom and the cavity field is produced by means of the atom-cavity interaction described by ...

Quantum computers? So… what IS a quantum computer? It’s a computer just like the ones you use now… but which operates internally on very different principles. What stays the same? interface: touchscreen, mouse+keyboard; inputs/outputs: numbers, text files, images, databases...; what is...
To establish a one-to-one correspondence to DE and QW, we should be able to show that the discretization of DE (or DH) will also lead to operator form identical to the QW evolution operators along with showing the transition of QW to DE in continuum limit. In this direc- tion, one ...
Using large-scale quantum Monte Carlo simulations of the spin-1/2 Hubbard model at half-filling on the honeycomb lattice, we show that for intermediate interaction strengths a gapped, non-magnetic phase destroys the semimetal before the transition to an antiferromagnetically ordered Mott insulator ...

The topological band structure of these materials can be fine-tuned by changing dopant ions, substrates and external gate voltages, which will enable also the control of the topological quantum phase transition. In particu- lar, we energy pgraepdiacbtotuhtat0.L1a5A euVO, w3 hbiiclahyeisr...
