Quantum Computing rithms are input by a user, the com- puter then creates a multidimen- sional space where patterns and individual data points are housed. Quantum bits, or qubits, are the basic unit of information in quantum computing. Qubits use superposition to be in multiple states at one time. Binary bits can only represent 0 or 1. Qubits can be 0 or 1, as well as any part of 0 and 1 in superposition of both states. Qubits can be made from trapped ions, photons, artificial or real atoms or quasiparticles, while binary bits are often silicon-based chips. Quantum superposition occurs when quantum particles are a combination of all possible states. The particles continue to fluctuate and move while the quantum computer meas- ures and observes each particle. Quantum particles are able to corre- spond measurements with one an- other, and when they are engaged in this state, it’s called entanglement. During entanglement, measurements from one qubit can be used to reach conclusions about other units. Entan- glement helps quantum computers solve larger problems and calculate bigger stores of data and information. As qubits experience superposition, they can also naturally experience quantum interference. This interfer- ence is the probability of qubits col- lapsing one way or another. Because of the possibility of interference, quantum computers work to reduce it and ensure accurate results. ISSUE 170 FEBRUARY 2023 the BANKING EXECUTIVE 9
