A system-on-a-chip (SoC) is an integrated circuit that combines multiple components, such as a microprocessor, memory, and I/O interfaces, onto a single chip. SoCs are used in many applications, such as smartphones, tablets, and embedded systems. Find out about us Quantum cryptography is a subfield of cryptography that uses principles of quantum mechanics to secure communication. Quantum cryptography can provide provably secure communication channels, even against an eavesdropper with unlimited computational power. Quantum key distribution is one of the most well-known applications of quantum cryptography. Popular quantum cryptography platforms include ID Quantique, Toshiba, and QuintessenceLabs.
