EVANSTON, ILLINOIS -- APRIL 25, 2011 -- NuCrypt, LLC has been invited to display their line of quantum optical test and measurement equipment at the Technology Transfer Showcase to be held at CLEO: 2011 Laser Science to Photonic Applications in Baltimore, MD on May 5th 2011. NuCrypt recently introduced their Entangled Photon Generation and Measurement system, the first complete suite of equipment for generating and measuring entangled quantum states, with a successful live demonstration at the "Updating Quantum Cryptography and Communications" (UQCC 2010) conference in Tokyo, Japan October 18-20th. Quantum optics has attracted significant research attention recently due in part to exciting potential applications in cryptography, computation, imaging, and communications. Optics are an ideal manifestation of quantum effects for many applications since photons, the quantum unit of light, can easily be transmitted over long distances in fiber or free-space. Other particles such as electrons are much harder to distribute.
Quantum effects can have strange consequences that are not describable by classical physics, such as the inherent instantaneous connection entangled states maintain even when separated by large distances. Laser light is at the border between quantum and classical descriptions. New types of optical sources such as entangled photon sources and on-demand single photon sources are necessary to exploit truly quantum effects.
NuCrypt has developed a polarization entangled photon source that is simple to operate. Customers have begun generating novel research results with the source, including a recent post-deadline paper at the 2010 Optical Fiber Communication (OFC) conference in a collaborative effort between AT&T Labs and university researchers in Italy and Israel. "Although customers like the performance and convenience of our entangled source, we found that a lot of time, money, and lab space was being consumed piecing together the auxiliary equipment needed to make measurements. By developing a set of compatible instrument-grade quantum measurement equipment, customers can now enjoy a streamlined system that operates right out-of-the-box", says Gregory Kanter, Vice President of NuCrypt.
NuCrypt's suite of equipment includes an entangled photon source, an electronically controlled polarization analyzer, and a correlated single photon detection system. Operating together they allow entangled photon pairs to be generated, separated, propagated through different lengths of optical fiber, passed through a polarizer of arbitrary polarization, then counted and correlated. Although each photon is un-polarized, their quantum nature readily appears when observing correlations between their arrivals. Unfortunately, the very appeal of quantum states, that they contain a dense amount of information that often only materializes in a statistical sense, usually makes them difficult to measure. However, multiple measurements in different orientations or "bases" can reveal their true nature. The NuCrypt system automates these normally complex measurement procedures.
In addition to providing laboratory-grade equipment, NuCrypt seeks licensing partners for applications of quantum optics. Critical quantum tools such as single-photon detectors and entangled photon sources can be leveraged to realize applications in quantum information and quantum metrology.
