Mahatma Gandhi Institute of Technology
'QUBIT' is the annual technical fest of the Department of Computer Science. It is a prestigious technological event in the state with papers presented from all over the country. It has risen beyond its technical reach and incorporated cultural aspects with the introduction of Lan-Gaming, Treasure Hunts, Fun Stalls etc. giving it an all round reach. It is organised during the month of March right from the year of its inception without fail. It is a technical symposium for young minds and meeting ground for tech-enthusiasts from around the country.
Superdense coding
In quantum information theory, superdense coding is a quantum communication protocol to transmit two classical bits of information (i.e., either 00, 01, 10 or 11) from a sender (often called Alice) to a receiver (often called Bob), by sending only one qubit from Alice to Bob, under the assumption of Alice and Bob pre-sharing an entangled state. This protocol was first proposed by Bennett and Weisner in 1992 and experimentally actualized in 1996 by Mattel, Weinfurter, Kwiat and Zeilinger using entangled photon pairs. By performing one of four quantum gate operations on the (entangled) qubit she possesses, Alice can prearrange the measurement Bob makes. After receiving Alice's qubit, operating on the pair and measuring both, Bob has two classical bits of information. If Alice and Bob do not already share entanglement before the protocol begins, then it is impossible to send two classical bits using 1 qubit, as this would violate Holevo's theorem.
