Additionally, the Federal Vision for Quantum Information Science (QIS) published by the National Science and Technology Council states that \"QIS promises to have important implications not only for national security but also for future economic competitiveness in areas ranging from wholly new and innovative technologies to improvements in global positioning systems and everyday concerns like healthcare.\" High purity heralded single photon and entangled photon states will also propel promising research efforts such as linear optical quantum computing, generation of optical Schrodinger cat states, and teleportation-based quantum repeaters for quantum key distribution over unlimited distance.
A waveguide based source of spectrally and spatially pure heralded photons will contribute to a wide range of NASA's advanced technology development efforts including on-demand single photon sources for high rate, spaced-based secure communications e.g. quantum key distribution, quantum metrology for precision space based navigation, quantum computation, and space-based entanglement distribution that can contribute to fundamental tests of quantum mechanical principals over large distances and probe the relationship between quantum and gravitational theories. In addition heralded single photon sources will be useful for the characterization, optimization, and calibration of detectors designed for photon starved operation and used in laser-based long distance communications.","description":"In this NASA SBIR Phase II effort, AdvR will design and build an efficient, fully integrated, waveguide based, source of spectrally uncorrelated photon pairs that will enable accelerated research and development in the emerging field of quantum information science. The key innovation is the use of sub-micron periodically poled waveguides to produce counter propagating photon pairs using quasi-phase matched downconversion. This novel device will provide a high brightness source of downconversion pairs with enhanced spectral properties, low attenuation, and operation in the visible to the mid-infrared spectral region.","startYear":2011,"startMonth":6,"endYear":2014,"endMonth":5,"statusDescription":"Completed","principalInvestigators":[{"contactId":3164163,"canUserEdit":false,"firstName":"Tony","lastName":"Roberts","fullName":"Tony Roberts","fullNameInverted":"Roberts, Tony","primaryEmail":"roberts@advr-inc.com","publicEmail":true,"nacontact":false},{"contactId":29357,"canUserEdit":false,"firstName":"Anthony","lastName":"Roberts","fullName":"Anthony Roberts","fullNameInverted":"Roberts, Anthony","primaryEmail":"roberts@advr-inc.com","publicEmail":true,"nacontact":false}],"programDirectors":[{"contactId":206378,"canUserEdit":false,"firstName":"Jason","lastName":"Kessler","fullName":"Jason L Kessler","fullNameInverted":"Kessler, Jason L","middleInitial":"L","primaryEmail":"jason.l.kessler@nasa.gov","publicEmail":true,"nacontact":false}],"programExecutives":[{"contactId":215154,"canUserEdit":false,"firstName":"Jennifer","lastName":"Gustetic","fullName":"Jennifer L Gustetic","fullNameInverted":"Gustetic, Jennifer L","middleInitial":"L","primaryEmail":"jennifer.l.gustetic@nasa.gov","publicEmail":true,"nacontact":false}],"programManagers":[{"contactId":62051,"canUserEdit":false,"firstName":"Carlos","lastName":"Torrez","fullName":"Carlos Torrez","fullNameInverted":"Torrez, Carlos","primaryEmail":"carlos.torrez@nasa.gov","publicEmail":true,"nacontact":false}],"projectManagers":[{"contactId":3164245,"canUserEdit":false,"firstName":"Jeffrey","lastName":"Wilson","fullName":"Jeffrey Wilson","fullNameInverted":"Wilson, Jeffrey","primaryEmail":"Jeffrey.D.Wilson@nasa.gov","publicEmail":true,"nacontact":false},{"contactId":461333,"canUserEdit":false,"firstName":"Theresa","lastName":"Stanley","fullName":"Theresa M Stanley","fullNameInverted":"Stanley, Theresa M","middleInitial":"M","primaryEmail":"theresa.m.stanley@nasa.gov","publicEmail":true,"nacontact":false}],"website":"","libraryItems":[],"transitions":[{"transitionId":66288,"projectId":9468,"partner":"Other","transitionDate":"2011-06-01","path":"Advanced From","relatedProjectId":9050,"relatedProject":{"acronym":"","projectId":9050,"title":"High Fidelity Down-Conversion Source for Secure Communications using On-Demand Single Photons","startTrl":3,"currentTrl":4,"endTrl":4,"benefits":"Quantum-based communication is of prime interest to corporations and government agencies with high security requirements. In cases where classical schemes are not considered trustworthy, key distribution by courier is typically used. Unlike human courier networks, quantum cryptography has the ability to detect interception of the key, has greater reliability and operating costs, and is automatic and instantaneous. For long distance quantum communication to be practical, ground-to-space links are a necessity due to the current limitations of optical fiber and photon detectors in ground-to-ground links. Another application is all-optical quantum computing (i.e. linear optical quantum computing), where the lack of high-purity on-demand photon sources is the biggest obstacle.
Satellite-based links established using on-demand single photon sources could provide a global quantum network. Additionally, a space-based implementation of the technology will answer important questions in fundamental physics by testing the properties of quantum entanglements over much greater distances than ever before, and due to earth's gravitational curvature may even provide an insight to the relationship between gravity and quantum physics.","description":"To provide reliably secure communications, development of quantum optical devices for encrypted ground-to-space communications is a necessity. The overall goal of this NASA effort is to develop and deliver efficient, single-pass quantum optical waveguide sources capable of backward quasi-phase-matched interactions for generation of high purity photon pairs for use in an on-demand photon source to enable high-rate long-distance encryption key distribution. The new devices will produce down-conversion entangled photon pairs with enhanced spectral properties and low attenuation, providing the key technology required for development of an on-demand heralded photon source. Furthermore, the waveguide-based technology is compact, robust, and power efficient for future deployment on space-based platforms to provide provably, unconditionally secure quantum encryption to satisfy requirements for the NASA topic Transformational Communications Technology.","startYear":2010,"startMonth":1,"endYear":2010,"endMonth":7,"statusDescription":"Completed","website":"","program":{"acronym":"SBIR/STTR","active":true,"description":"
The NASA SBIR and STTR programs fund the research, development, and demonstration of innovative technologies that fulfill NASA needs as described in the annual Solicitations and have significant potential for successful commercialization. If you are a small business concern (SBC) with 500 or fewer employees or a non-profit RI such as a university or a research laboratory with ties to an SBC, then NASA encourages you to learn more about the SBIR and STTR programs as a potential source of seed funding for the development of your innovations.
The SBIR and STTR programs have 3 phases:
The SBIR and STTR Phase I contracts last for 6 months with a maximum funding of $125,000, and Phase II contracts last for 24 months with a maximum funding of $750,000 - $1.5 million.
Opportunity for Continued Technology Development Post-Phase II:
The NASA SBIR/STTR Program currently has in place two initiatives for supporting its small business partners past the basic Phase I and Phase II elements of the program that emphasize opportunities for commercialization. Specifically, the NASA SBIR/STTR Program has the Phase II Enhancement (Phase II-E) and Phase II eXpanded (Phase II-X) contract options.
