Resolve problems that cannot be efficiently calculated with existing supercomputers to quickly solve problems in areas where answers were difficult to find
A quantum computer is a computer processing device proposed to use the characteristics of quantum mechanics to solve computational problems in areas that are impossible or difficult to process with classical computers.
The quantum mechanical principles that form the basis of quantum computers are quantum superposition, observational collapse, and quantum entanglement.
In classical information devices, information is expressed as 0 or 1, and the quantum state can express information in the form of a simultaneous linear combination of 0 and 1. This feature is also expressed as 'quantum parallelism'.
Observation causes irreversible changes in the quantum state, preventing the original quantum state from being restored after measurement and making replication impossible. This ensures information security by perfectly preventing external measurement, making it widely applicable in the field of quantum cryptography.
In the phenomenon where if one state is determined in two or more quantum states, the other dependent states are determined accordingly, interference occurs between spatially separated information in the process of information processing and communication.
Recognizes either 0 or 1 as a unit of information called a bit for computation. With 2 bits, it processes only one piece of information among 00, 01, 10, or 11.
Performs operations using bits (qubits) of quantum states where 0 and 1 exist simultaneously. With 2 qubits, the 4 pieces of information 00, 01, 10, 11 exist simultaneously. Problems that take hundreds of millions of years to solve with supercomputers can be calculated in just a few hours.
