How a 4,500-Qubit Quantum Machine Learned to Remember Time
A 4,500-qubit quantum annealer turns its native spin dynamics into a memory system for learning patterns in chaotic time series.
The Quantum Searchlight That Finds a Signal Without Scanning
A superconducting cavity uses Grover’s search to identify an unknown signal frequency, but scaling the quantum sensor remains difficult.
