| Decoherence |
The loss of coherence or information in a quantum system occurs when it interacts with the external environment. |
| Eavesdropping |
The unauthorized interception of communication intended for other parties, a major concern in quantum cryptography. |
| Entanglement |
In quantum computing, there is a phenomenon where two or more qubits establish a correlation and effortlessly share information. |
| Hadamard Gate |
A quantum gate transforms a qubit from the base states to a superposition state with equal probability of different outcomes. |
| Quantum Algorithm |
A collection of instructions or operations designed to be executed on a quantum computer in order to solve particular problems. |
| Quantum Bits (Qubits) |
The basic unit of quantum information, similar to classical bits but can be in a superposition of both 0 and 1 states. |
| Quantum Computing |
Computing that harnesses the principles of quantum mechanics to carry out computations. |
| Quantum Cryptography |
A branch of cryptography that uses principles of quantum mechanics to secure communication. |
| Quantum Error Correction |
In quantum computing, a method is employed to safeguard against errors and decoherence that may occur throughout the computation process. |
| Quantum Gate |
A fundamental element of quantum circuits that manipulates qubits with the purpose of executing precise operations. |

A method of transmitting cryptographic keys using quantum communication channels. |
| Quantum Supremacy |
The stage at which quantum computers can outperform classical computers in solving specific problems. |
| Quantum-Resistant Cryptography |
Cryptography algorithms designed to remain secure against attacks from quantum computers. |
| Qubit |
"The essential information unit in quantum computing is known as a quantum bit, or simply a quantum bit. It possesses the ability to symbolize the values 0 or 1, or exist in a state of superposition encompassing both." |
| Superposition |
In the context of quantum computing, the fundamental concept of existing in multiple states simultaneously is observed by a qubit. |
