Stocks in Focus with Breakthrough Developments in Sector

Quantum computing has the potential to be the biggest technological disruption of our lifetime and Archer Materials, D-Wave Quantum, Rigetti Computing are at the heart of this revolution that is turning science fiction into investable reality.

Archer Materials Limited (ASX: AXE)

is leading Australia’s move into quantum computing and new semiconductor tech. It made good progress in its 12CQ quantum project which is a room temperature carbon-based qubit technology that can change the future of computing power. The company reached an important milestone by showing strong connection between spin states and superconducting resonators, this step allows better control of qubits which is very important for building large scale quantum processors. The team also worked with EPFL in Switzerland and Queen Mary University of London to improve spin coherence time and device design, which means the quantum features can now work closer to normal room conditions, a big step ahead in this area. Archer is also working on tunnelling magnetoresistance sensors for AI, cars and Internet of Things which can help make money sooner. The company has about A$13.7 million dollars in cash and no debt which gives it a strong position to keep growing in both quantum and biosensing fields. With more than 30 global patents in quantum and biochip ideas Archer is laying the base for the next age of computing sensing and health technology.

D Wave Quantum Inc (NYSE: QBTS)

In September 2025 worked with North Wales Police on a proof of technology project that used D Wave’s hybrid quantum system to plan and assign police vehicles more efficiently. The result was impressive because response times were almost 50 percent faster and coordination time dropped from four months to just four minutes. This clearly showed that quantum algorithms can perform better than normal computers when handling complex and time sensitive decisions. The company has about US$819 million in cash, no short term debt, and more than 100 active customers, which strengthens its place in global quantum computing. Its focus on hybrid solvers, AI integration and partnerships with public sectors shows that D Wave wants to make quantum computing useful as soon as possible.

Rigetti Computing Inc (NASDAQ: RGTI)

is growing its reach in hybrid quantum computing with a new collaboration that could put it ahead in the next tech revolution. On 2 September 2025, it signed an MOU with India’s Centre for Development of Advanced Computing (C-DAC) to work together on hybrid quantum systems for government and research use. This deal brings together C-DAC’s strong high performance computing skills and Rigetti’s know-how in superconducting quantum chips. The goal is to build scalable, real-world systems and help train more people in quantum technology. Rigetti’s chips which run on superconducting qubits are said to be over 1000 times faster and are moving towards multi-chip setups that could cross 100 qubits. Financially the company is in a solid spot with about US$57 million in cash. It even turned profitable recently showing a net income of around US$3 million for H1 2025. With strong global tie ups and new hardware progress Rigetti looks to be shifting fast from just research to becoming a big name in quantum computing.
