What is IBM Quantum Heron & Condor (Quantum System Two)?

Quantum computers store information in qubits, which can hold a blend of two states, and use effects such as interference to favour the right answer; they may help with tasks like physical simulations, and qubits lose their state when disturbed by their surroundings. IBM Quantum Heron is a family of quantum processor chips whose first version had 133 qubits, and IBM Condor is a 1,121-qubit processor. IBM Quantum System Two is the machine around such chips: cooling infrastructure that holds qubits near absolute zero, classical servers and modular control electronics that let quantum chips work alongside ordinary computers. IBM debuted Heron and System Two on 4 December 2023.
