Linear optical quantum computing with photonic qubits
Linear optics with photon counting is a prominent candidate for practical quantum computing. The protocol by Knill, Laflamme, and Milburn [2001, Nature (London) 409, 46] explicitly demonstrates that…
Objectively discerning Autler-Townes splitting from electromagnetically induced transparency.
An objective method is introduced, based on Akaike's information criterion, to test ATS vs EIT from experimental data for three-level atomic systems and determine which pertains, and applies to a recently reported induced-transparency experiment in superconducting-circuit quantum electrodynamics.
Quantum optical metrology – the lowdown on high-N00N states
- J. Dowling
- 1 March 2008
Quantum states of light, such as squeezed states or entangled states, can be used to make measurements (metrology), produce images, and sense objects with a precision that far exceeds what is…
The photonic band edge laser: A new approach to gain enhancement
Near the band edge of a one‐dimensional photonic band gap structure the photon group velocity approaches zero. This effect implies an exceedingly long optical path length in the structure. If an…
Quantum technology: the second quantum revolution
A number of examples of research programs that could deliver quantum technologies in coming decades including: quantum information technology, quantum electromechanical systems, coherent quantum electronics, quantum optics and coherent matter technology are discussed.
Quantum metrology with two-mode squeezed vacuum: parity detection beats the Heisenberg limit.
In this setup, dependence of the signal on the phase evolves n times faster than in traditional schemes, and uncertainty in the phase estimation is better than 1/n, and the quantum Cramer-Rao bound is saturate.

- 7 June 1996
An exact expression for the electromagnetic mode density, and hence the group velocity, is derived for a finite N period, one-dimensional photonic band-gap structure and applications to 3D structures, spontaneous emission control, delay lines, band-edge lasers, and superluminal tunneling times are discussed.
A quantum Rosetta stone for interferometry
Heisenberg-limited measurement protocols can be used to gain an increase in measurement precision over classical protocols. Such measurements can be implemented using, for example, optical…
Transparent, metallo-dielectric, one-dimensional, photonic band-gap structures
We investigate numerically the properties of metallo-dielectric, one-dimensional, photonic band-gap structures. Our theory predicts that interference effects give rise to a new transparent metallic…
