1 ebit + 2 bits 1 qubit (i.e. quantum teleportation), where ⩾ {\displaystyle \geqslant } indicates "can do the job of". These principles were formulated around 1993 by Charles H. Bennett .
Michael Peter Barnett (24 March 1929 – 13 March 2012) was a British theoretical chemist and computer scientist. [1] He developed mathematical and computer techniques for quantum chemical problems, and some of the earliest software for several other kinds of computer application.
BB84 is a quantum key distribution scheme developed by Charles Bennett and Gilles Brassard in 1984. [1] It is the first quantum cryptography protocol. [2] The protocol is provably secure assuming a perfect implementation, relying on two conditions: (1) the quantum property that information gain is only possible at the expense of disturbing the signal if the two states one is trying to ...
Just like the basic unit of classical information is the bit, quantum information deals with qubits. [15] Quantum information can be measured using Von Neumann entropy. Recently, the field of quantum computing has become an active research area because of the possibility to disrupt modern computation, communication, and cryptography. [14] [16]
But the no-hiding theorem is a more general proof of conservation of quantum information which originates from the proof of conservation of wave function in quantum theory. It may be noted that the conservation of entropy holds for a quantum system undergoing unitary time evolution and that if entropy represents information in quantum theory ...
Joan Vaccaro is a physicist at Griffith University and a former student of David Pegg.Her work in quantum physics includes quantum phase, [1] nonclassical states of light, coherent laser excitation of atomic gases, cold atomic gases, stochastic Schrödinger equations, quantum information theory, quantum references, wave–particle duality, quantum thermodynamics, and the physical nature of time.
"The six-state protocol is a discrete-variable protocol for quantum key distribution that permits tolerating a noisier channel than the BB84 protocol." [ 3 ] (2011, Abruzzo). SSP produces a higher rate of errors during attempted eavesdropping, thus making it easier to detect errors, as an eavesdropper must choose the right basis from three ...
Charles Henry Bennett (born 1943) [1] is a physicist, information theorist and IBM Fellow at IBM Research.Bennett's recent work at IBM has concentrated on a re-examination of the physical basis of information, applying quantum physics to the problems surrounding information exchange.
