IBM Quantum Computer Roadmap | NextBigFuture.com

IBM has published a roadmap for improving quantum computers based upon a “quantum volume” metric. IBM defined quantum volume in 2017. A quantum computer’s performance depends on many factors that can make assessing its power challenging. These factors include: 1. The number of physical qubits; 2. The number of gates that can be applied before errors make the device behave essentially classically; 3. The connectivity of the device; 4. The number of operations that can be run in parallel. Quantum volume is an architecture-neutral metric. It measures the useful amount of quantum computing done by a device in space and
