Ebit

9.9
A unit that measures how much two quantum particles are linked by entanglement
  • noun
  • /ˈiːbɪt/
  • Specialized
translation icon : ebit
  • In quantum information theory, one ebit represents the maximum entanglement possible between two qubits.

Examples

  • Note that ebits are an undirected resource, shared symmetrically between two remote parties, while qubits and bits have a definite direction, passing from a sender to a receiver.

  • The second line means that an ebit of shared entanglement can be created given the ability to send a qubit (for example, by having one observer prepare an EPR pair and send half of it to the other observer).

    Academic text (1995)
  • Each ebit can be utilized to perform operations that require shared quantum information between distant systems.

  • When measuring the entanglement, it is essential to recognize how many ebits are present in the quantum state.

Etymology

In quantum information, Ebit is formed from e- for 'entanglement' and bit, so an Ebit is one 'entangled bit' shared between two systems and is used to measure how strongly they are linked.
