3 Top Quantum Computing Stocks to Buy in 2026

The race for quantum dominance is no longer theoretical as it enters commercialization phase and these three companies represent the best opportunities for investors in 2026.

Archer Materials Limited (ASX: AXE)

on 20 November 2025 announced that it achieved electrical control of its quantum device which improved the chip’s capability to detect and read quantum information.

The company also confirmed that this progress de risks its carbon film pathway for scalable manufacturing and has already commenced the next phase of spin state readout testing under magnetic fields while early results are expected soon.

Archer on 10 November 2025 announced that it entered into an agreement with CSIRO to develop Quantum Machine Learning models which are aimed at fraud detection in financial transactions.

The company also reported that its silicon-based blood potassium graphene biochip developed with IMEC met key performance and clinical accuracy requirements which represents the first major step towards development and commercialisation for the lead application of Archer’s Biochip platform.

Archer had cash deposits of $11.6 million at the end of the September 2025 quarter and no outstanding debt.

IonQ, Inc. (NYSE: IONQ)

completed the acquisition of Oxford Ionics in September 2025 for US$1.59 billion which strengthens trapped ion hardware roadmap and is expected to improve qubit fidelity and scalability.

IonQ reported strong revenue growth with US$68.1 million for the first nine months of 2025 compared to US$31.4 million in the same period last year.

The company has a robust liquidity position with US$346 million in cash and US$736 million in short-term investments which provides substantial capacity to support research, development and expansion.

The company’s strategy is focused on scaling higher fidelity trapped ion systems, quantum networking including satellite based secure communication infrastructure and enterprise adoption through cloud platforms.

The technology from Oxford Ionics is expected to be a key contributor to next generation hardware which is planned for rollout in 2026.

D-Wave Quantum Inc. (NYSE: QBTS)

has emerged as one of the strongest commercial quantum computing companies after a sharp acceleration in revenue.

The company’s sixth generation annealing system Advantage2 is gaining traction as customers deploy it for real world optimization use cases.

D Wave reported US$21.8 million revenue for the first nine months of 2025 compared to US$6.5 million in the prior year period and gross profit surged to US$18.5 million.

The balance sheet strengthened as cash and cash equivalents rose to US$836 million by September 30 2025 which provides enough capital for future growth.

Key catalysts include further system sales to governments and research institutions along with expansion of hybrid quantum applications in logistics and potential progress in gate model development alongside annealing leadership.
