Google’s Quantum Computing Uses Electrons and Photons as Information Carriers

The physical implementation of qubits utilizes fundamental particles whose quantum properties enable computation. Electrons and photons are among the particle types used to encode quantum information.
Different particle types offer various advantages and disadvantages for quantum computing. Electrons can be trapped and controlled using electromagnetic fields, while photons can travel long distances without significant interference.
The choice of particle type influences the overall quantum computer architecture. Hardware design must accommodate the specific properties and requirements of the chosen qubit implementation.
Controlling individual particles with sufficient precision to perform quantum computations requires sophisticated technology. Laser systems, microwave generators, and other specialized equipment manipulate qubit states.
The quantum properties of these particles, established by fundamental physics, cannot be changed. Instead, engineering focuses on exploiting these properties effectively while managing their limitations.
Future quantum computers might employ multiple types of qubits within hybrid systems. Different particle types could be used for different purposes within a single quantum computing architecture.
