5.4 Quantum Devices Energy Levels in a Single Quantum Well
... We have used periodic boundary conditions for this case, which is physically sensible for large crystals. The wave functions are propagating plane waves in this case. It is, however, more common and sensible to use fixed boundary conditions, especially for small dimensions. The wave functions then a ...

Quantum Memories at Room-Temperature Supervisors: Dr Dylan
... in our lambda Raman quantum memory. This will be demonstration of a new protocol: a quantum Zeno noise suppression technique to kill a noise-process prohibits quantum operation, a process known as four-wave-mixing. We will suppress two-mode-squeezing via incoherent Hamiltonian engineering. This work ...
