Quantum computing
Quantum computing is a field of computing that utilizes quantum mechanical phenomena to perform calculations. Quantum computers use qubits, which can exist in superpositions of states, allowing them to solve certain problems exponentially faster than classical computers, although practical applications are still largely experimental.
Qubit
The fundamental unit of information in quantum computing, capable of being in multiple states simultaneously.
Quantum entanglement
A quantum mechanical phenomenon where pairs of qubits remain interconnected regardless of distance.
Action at a distance
Action at a distance refers to the concept where an object can affect another without physical contact, an idea historically linked to gravity and quantum mechanics.
AdS/CFT correspondence
The AdS/CFT correspondence is a theoretical relationship between anti-de Sitter spaces and conformal field theories, providing insights into quantum entanglement.
Albert Einstein
A pioneering physicist who contributed fundamental theories to quantum mechanics and challenged quantum entanglement concepts.
Quantum supremacy
The theoretical ability of a quantum computer to solve problems that classical computers cannot solve in a reasonable timeframe.
Quantum advantage
The milestone where quantum computers outperform classical computers for specific tasks.
Adiabatic quantum computation
Adiabatic quantum computation is a form of quantum computing that relies on the adiabatic theorem for calculations.
Adiabatic theorem
A quantum mechanical theorem describing how systems change when gradually perturbed.
Amplitude amplification
A quantum computing technique that generalizes Grover's search algorithm, providing quadratic speedup.
