We report the continuous and partially nondestructive measurement of optical photons. For a weak light pulse traveling through a slow-light optical medium (signal), the associated atomic-excitation component is detected by another light beam (probe) with the aid of an optical cavity. We observe strong correlations of g_{sp}^{(2)}=4.4(5) between the transmitted signal and probe photons. The observed (intrinsic) conditional nondestructive quantum efficiency ranges between 13% and 1% (65% and 5… Expand
Large conditional single-photon cross-phase modulation
TLDR
A large conditional cross-phase modulation between a signal field, stored inside an atomic quantum memory, and a control photon that traverses a high-finesse optical cavity containing the atomic memory is demonstrated, enabling deterministic and universal photonic quantum logic. Expand

Observation of Collective Superstrong Coupling of Cold Atoms to a 30-m Long Optical Resonator.
TLDR
The measured transmission spectra of the coupled atom-resonator system provide evidence of this regime, realized with a few hundred atoms with an intrinsic single-atom cooperativity of 0.13, the starting point for studies in a new setting of light-matter interaction, with strong quantum nonlinearities and a new type of dynamics.

Nondestructive Detection of an Optical Photon
TLDR
An experimental system capable of detecting a single photon without destroying it is described and the large single-photon nonlinearity of the experiment should enable the development of photonic quantum gates and the preparation of exotic quantum states of light. Expand
Seeing a single photon without destroying it
Light detection is usually a destructive process, in that detectors annihilate photons and convert them into electrical signals, making it impossible to see a single photon twice. But this limitationExpand
Quantum nondemolition measurement of the photon number via the optical Kerr effect.
TLDR
The measurement accuracy and the imposed phase noise of the signal wave satisfy Heisenberg's uncertainty principle with an equality sign, and a quantum nondemolition measurement scheme for the photon number is proposed. Expand
Controlled Phase Shifts with a Single Quantum Dot
TLDR
It is shown that a single quantum dot coupled to a photonic crystal nanocavity can facilitate controlled phase and amplitude modulation between two modes of light at the single-photon level. Expand
Quantum nonlinear optics with single photons enabled by strongly interacting atoms
TLDR
This work demonstrates a medium that is nonlinear at the level of individual quanta, exhibiting strong absorption of photon pairs while remaining transparent to single photons, paving the way for quantum-by-quantum control of light fields, including single-photon switching, all-optical deterministic quantum logic and the realization of strongly correlated many-body states of light.

Cross modulation of two laser beams at the individual-photon level.
TLDR
This work uses an atomic ensemble inside a cavity to demonstrate the mutual cross modulation of two continuous light beams at the level of individual photons, and shows that one photon in one beam extinguishes a photon in the other beam with a probability of 11(1)%. Expand
Quantum jumps of light recording the birth and death of a photon in a cavity
TLDR
An experiment in which quantum jumps in the photon number are observed and a similar QND procedure to mesoscopic fields with tens of photons is applied, which should open new perspectives for the exploration of the quantum-to-classical boundary. Expand
All-Optical Switch and Transistor Gated by One Stored Photon
TLDR
By stopping a light pulse in an atomic ensemble contained inside an optical resonator, the realization of an all-optical transistor is realized, in which one stored gate photon controls the resonator transmission of subsequently applied source photons. Expand
Nearly deterministic linear optical controlled-NOT gate.
TLDR
The key element of this gate is nondemolition detectors that use a weak cross-Kerr nonlinearity effect to conditionally generate a phase shift on a coherent probe if a photon is present in the signal mode. Expand
