Circuits Quantum Electrodynamics (cQED)

Circuit Quantum Electrodynamics (cQED) is a field that studies the interaction between quantum bits (qubits)—the building blocks of quantum computers—and microwave photons within superconducting circuits. Imagine tiny superconducting circuits acting like artificial atoms, which can be precisely controlled and measured. These circuits enable scientists to observe, manipulate, and utilize quantum phenomena such as superposition and entanglement, essential for quantum computing. cQED provides a platform to develop scalable quantum processors by integrating qubits with microwave resonators, allowing for strong, controllable interactions vital for processing quantum information efficiently.
