Photo-detection plays a fundamental role in experimental quantum optics and is of particular importance in the emerging field of linear optics quantum computing. Present theoretical treatment of photo-detectors is highly idealized and fails to consider many important physical effects. We present a physically motivated model for photo-detectors which accommodates for the effects of finite resolution, bandwidth and efficiency, as well as dark counts and dead-time. We apply our model to two simple… 

Theoretical comparison of quantum and classical illumination for simple detection-based LIDAR

Use of non-classical light in a quantum illumination scheme provides an advantage over classical illumination when used for LIDAR with a simple and realistic detection scheme based on Geiger-mode

Photonic Astronomy and Quantum Optics

Quantum optics potentially offers an information channel from the Universe beyond the established ones of imaging and spectroscopy. All existing cameras and all spectrometers measure aspects of the

Time-resolved detection and mode mismatch in a linear optics quantum gate

Linear optics (LO) is a promising candidate for the implementation of quantum information processing protocols. In such systems, single photons are used to represent qubits. In practice, single

Photon number projection using non-number-resolving detectors

Number-resolving photo-detection is necessary for many quantum optics experiments, especially in the application of entangled state preparation. Several schemes have been proposed for approximating

Gaussian state-based quantum illumination with simple photodetection.

The continuous-variable Gaussian quantum information formalism is used to show that quantum illumination is better for object detection compared with coherent states of the same mean photon number, even for simple direct photodetection.

Gaussian state-based quantum illumination with simple photodetection

: Proofs of the quantum advantage available in imaging or detecting objects under quantum illumination can rely on optimal measurements without specifying what they are. We use the

Engineering quantum jump superoperators for single-photon detectors

We study the back action of a single-photon detector on the electromagnetic field upon a photodetection by considering a microscopic model in which the detector is constituted of a sensor and an

Optical quantum computing with photons of arbitrarily low fidelity and purity

It is presented evidence that by increasing the size of the system the authors can implement a computationally hard algorithm even if their photons have arbitrarily low fidelity and purity, and make Boson-sampling LOQC within reach of present-day technology.

Experimental demonstration of full-field quantum optical coherence tomography

We present, to the best of our knowledge, the first implementation of full-field quantum optical coherence tomography (FF-QOCT). In our system, we are able to obtain full three-dimensional (3D)

Accurate and precise characterization of linear optical interferometers

We combine single- and two-photon interference procedures for characterizing any multi-port linear optical interferometer accurately and precisely. Accuracy is achieved by estimating and correcting



Photon counting schemes and performance of non-deterministic nonlinear gates in linear optics

The performance of nondeterministic nonlinear gates in linear optics relies on the photon counting scheme being employed and the efficiencies of the detectors in such schemes. We assess the

Fiber-assisted detection with photon number resolution.

The development of a photon-number-resolving detector based on a fiber-optical setup and a pair of standard avalanche photodiodes is reported, showing that there is a high probability of inferring the input photon number from a measurement of the number of detection events on a single run.

Development of a high-quantum-efficiency single-photon counting system

A high-quantum-efficiency single-photon counting system has been developed. In this system, single photons were detected by a visible light photon counter operated at 6.9 K. The visible light photon

A scheme for efficient quantum computation with linear optics

It is shown that efficient quantum computation is possible using only beam splitters, phase shifters, single photon sources and photo-detectors and are robust against errors from photon loss and detector inefficiency.

A novel method for characterizing the mode structure of single photons, and demonstrating it in the context of coherent light, is described and demonstrated.

Multiphoton detection using visible light photon counter

Visible light photon counters feature noise-free avalanche multiplication and narrow pulse height distribution for single photon detection events. Such a well-defined pulse height distribution for a

In the preceding paper (Warszawski P and Wiseman H M 2002 J. Opt. B: Quantum Semiclass. Opt. 4 1) we presented a general formalism for determining the state of a quantum system conditional on the

Photon chopping: New way to measure the quantum state of light.

The use of a balanced $2N-port as a technique to measure the pure quantum state of a single-mode light field and the photon statistics can be measured with currently available devices.

Quantum trajectories for realistic photodetection: I. General formalism

The essential idea is to treat the quantum system and classical detector jointly, and to average over the latter to obtain the conditional quantum state, and the approach could be applied in many areas of physics.

Towards photostatistics from photon-number discriminating detectors

Abstract We study the properties of a photodetector that has a numberresolving capability. In the absence of dark counts, due to its finite quantum efficiency, photodetection with such a detector can
