D-Wave Quantum stock (QBTS) slides after $550 million Quantum Circuits deal puts dilution in focus
New York, January 7, 2026, 20:16 (EST) — Market closed D-Wave Quantum shares fell 3.4% to close at $30.20 on Wednesday after the quantum computing company announced a $550 million deal for Quantum Circuits. StockAnalysis The move matters now because D-Wave is trying to widen its pitch beyond quantum annealing — a specialised method used mainly for optimisation problems such as scheduling — and push harder into “gate-model” systems, the general-purpose approach most labs pursue. Gate-model machines run sequences of operations on qubits, the basic unit of quantum information. The deal followed a separate announcement on Tuesday in which D-Wave
