A single-photon source is a device that emits one photon at a time, crucial for applications in quantum computing, cryptography, and advanced photonic circuits. Achieving true single-photon emission is a challenging task that requires precise manipulation and control of quantum states to ensure reliability and efficiency.

Single-photon Source

Photon emission is the process by which an atom or molecule releases a photon, typically when an electron transitions from a higher energy level to a lower one. This fundamental mechanism is responsible for phenomena such as fluorescence, phosphorescence, and the emission of light from stars and other celestial bodies.

Photon Emission

Quantum computing leverages the principles of quantum mechanics to process information in ways that classical computers cannot, using qubits that can exist in multiple states simultaneously. This allows for potentially exponential increases in computing power, enabling solutions to complex problems in fields like cryptography, optimization, and materials science.

Quantum Computing

Cryptography is the science of securing communication and information through the use of mathematical techniques, ensuring confidentiality, integrity, authenticity, and non-repudiation. It plays a crucial role in various applications such as secure communications, digital signatures, and cryptocurrency, protecting data from unauthorized access and tampering.
