About Quantum Technology
The development of quantum technology has the potential to deliver exponential improvements in the performance of applications such as sensing, communication, computing, and timing. Based on many-particle quantum superposition and entanglement within large engineered systems, these technologies depend on high-performance light sources to operate effectively. AdvR’s LN, MgO:LN, and KTP materials are key enablers of the wavelength conversion essential for these advanced light sources.
Wavelength Engineering for Quantum Technology
AdvR non-linear optical materials are a key enabler for the high performance light sources needed for quantum applications.
Quantum Sensing
Quantum sensors harness quantum particles and their interactions to perform highly precise environmental measurements, offering sensitivities many orders of magnitude beyond conventional sensors. They can measure a wide range of physical properties, including frequency (for timing), magnetic and gravitational fields, linear and rotational acceleration (in inertial systems), electric fields (for RF detection), and even individual photons of light.
Quantum Communication
Quantum-enabled networking and communication are essential to advancing quantum computing and next-generation cryptography protocols. Quantum frequency conversion is critical for generating the precise wavelengths required for both fiber and free-space transmission of quantum information. AdvR’s devices also deliver high-efficiency photon-pair sources, forming the foundation of entangled photon sources (EPS) used in quantum key distribution (QKD) systems.
Quantum Computing
At the core of quantum computing lies the qubit, a unit that can represent 1, 0, or any state in between simultaneously. This property, known as superposition, enables multiple operations to be executed in parallel, delivering performance millions of times faster than classical computing. Quantum computing platforms, including neutral atom and photonic systems, depend on precisely engineered light sources for their operation.
Quantum Navigation and Timing
Quantum PNT (Position, Navigation, and Timing) leverages advanced quantum sensing and measurement technologies to overcome the limitations of GNSS in challenging environments such as urban areas, underground locations, or regions affected by GPS denial or interference. By integrating technologies including atomic clocks, inertial sensors, gravimeters, and magnetometers, Quantum PNT delivers robust, highly accurate positioning systems that operate independently of GPS.
