Improving quantum dot based single-photon source with continuous measurements
Anirudh Lanka, Todd Brun
We propose a technique to improve the probability of single-photon emission with an electrically pumped quantum dot in an optical microcavity, by continuously monitoring the energy…
Quantum Steganography via Coherent and Fock State Encoding in an Optical Medium
Bruno Avritzer, Todd Brun
Steganography is an alternative to cryptography, where information is protected by secrecy -- being disguised as innocent communication or noise -- rather than being scrambled. In…
Influence of coin symmetry on infinite hitting times in quantum walks
Prithviraj Prabhu, Todd A. Brun
Classical random walks on finite graphs have an underrated property: a walk from any vertex can reach every other vertex in finite time, provided they are connected. Discrete-time…
Fermionic and bosonic quantum field theories from quantum cellular automata in three spatial dimensions
Leonard Mlodinow, Todd A. Brun
Quantum walks on lattices can give rise to relativistic wave equations in the long-wavelength limit, but going beyond the single-particle case has proven challenging, especially in…
Quantum cellular automata and quantum field theory in two spatial dimensions
Todd A. Brun, Leonard Mlodinow
Quantum walks on lattices can give rise to one-particle relativistic wave equations in the long-wavelength limit. In going to multiple particles, quantum cellular automata (QCA) ar…
Quantum field theory from a quantum cellular automaton in one spatial dimension and a no-go theorem in higher dimensions
Leonard Mlodinow, Todd A. Brun
It has been shown that certain quantum walks give rise to relativistic wave equations, such as the Dirac and Weyl equations, in their long-wavelength limits. This intriguing result…
