Welcome back to This Week in Quantum — your weekly digest of the most important news from the world of quantum computing.
The week of May 23–30 was defined by hardware commitments at every level of the stack — from national manufacturing infrastructure to a chip that works at room temperature. IBM put a number on its quantum ambitions ($10 billion, 2029 deadline), D-Wave announced it is entering the gate-model race, and Stanford published results that could eventually eliminate cryogenic cooling from quantum devices entirely.
Industry News
IBM commits $10 billion to quantum computing and targets fault tolerance by 2029
In an SEC filing and subsequent investor briefings, IBM announced plans to invest more than $10 billion in quantum computing over the next five years — covering R&D, capital expenditures, ecosystem partnerships, manufacturing scaling, and M&A. The headline target: delivering the world’s first large-scale, fault-tolerant quantum computer in the second half of 2029.
The centrepiece of the plan is the Starling processor, designed to reach approximately 200 logical qubits running 100 million gates by 2029, followed by the Blue Jay processor in 2033 targeting 2,000 logical qubits and 1 billion gates. Both chips require 300mm fabrication — which is precisely what Anderon, IBM’s newly established quantum chip foundry, is being built to provide (announced the previous week as part of the $2 billion CHIPS Act package).
IBM also noted that it has deployed over 90 quantum systems globally, a fleet larger than all other quantum hardware providers combined, and that its Qiskit software is used by nearly 70% of quantum developers with over 4 trillion circuits run to date.
Infleqtion opens a Quantum Innovation Centre in Oxford
Infleqtion established a new Quantum Innovation Centre and manufacturing hub in Oxford, UK, expanding its European footprint to produce neutral-atom quantum computing and sensing hardware domestically. The facility is directly tied to the UK’s National Quantum Strategy — one of its first deliverables is a 100-qubit quantum computer for the National Quantum Computing Centre (NQCC), alongside atom-based sensing platforms for UK defense applications.
The Oxford hub positions Infleqtion as one of the few quantum companies with active manufacturing operations on both sides of the Atlantic.
D-Wave unveils gate-model roadmap targeting 100 logical qubits by 2032
At its first-ever Investor Day at the New York Stock Exchange, D-Wave unveiled a detailed gate-model development roadmap — a significant strategic expansion for a company previously known exclusively for quantum annealing systems.
The roadmap targets 100 logical qubits capable of performing over one million operations by 2032, built on a superconducting dual-rail qubit architecture with integrated quantum error correction. Key milestones include a 17-physical-qubit error-detecting system in 2026, a 49-qubit system with 20x error reduction in 2027, a 181-qubit system with 2,000x error reduction in 2028, and 10 logical qubits supporting the first fault-tolerant algorithms by 2030.
D-Wave CEO Alan Baratz framed the dual-rail architecture as “fundamentally different” from competitors, citing hardware-level error reduction as a path to reaching fault tolerance with fewer physical qubits per logical qubit. The gate-model chips will be integrated into D-Wave’s Leap quantum cloud service, making D-Wave the only company offering both annealing and gate-model quantum computing on a single platform.
Pramatra Space raises pre-seed funding for space-based QKD hardware
Pramatra Space, a Bengaluru-based quantum security startup, secured pre-seed investment from Seafund Ventures, Rebalance, and Magnivia Ventures to develop hardware for satellite-based Quantum Key Distribution. Space-based QKD can extend secure quantum communication links beyond the range of ground fiber networks, and India’s active space programme makes it a credible testing ground for early commercial deployment.
IISc launches Wadhwani Innovation Centre for quantum and deep-tech startups
The Indian Institute of Science in Bengaluru opened the Wadhwani-IISc Innovation Centre on May 22, funded by a collaborative Rs 1,400+ crore investment, to accelerate deep-tech research and quantum startup incubation. The centre’s InQubate platform targets quantum hardware commercialisation and aligns directly with India’s National Quantum Mission.
Research Highlights
Stanford: room-temperature quantum entanglement using twisted light
Researchers at Stanford University published results in Nature Communications showing a nanoscale optical device that entangles the spin of photons and electrons at room temperature — no cryogenic cooling required. The device uses a patterned layer of molybdenum diselenide atop a silicon substrate to generate twisted light: photons with angular momentum that can impart spin to electrons, creating stable entangled states.
The achievement sets a new room-temperature record for degree of circular polarization (0.5) for this class of devices. If the approach scales, it could eventually allow quantum hardware to be deployed outside specialised cryogenic facilities — making quantum components as practical as conventional electronics. Near-term applications include quantum-secure communications and distributed quantum networks.
University of Houston breaks 30-year superconductivity record at normal pressure
Scientists at the University of Houston created a material that conducts electricity with zero resistance at the highest temperature ever recorded under normal atmospheric pressure — shattering a record that had stood for 30 years. While not directly a quantum computing result, superconductivity is the physical basis of IBM’s, Google’s, and most other leading quantum processors. Higher-temperature superconductors could dramatically reduce the engineering complexity and cost of future quantum hardware.
Twisted graphene reveals a new superconductivity control switch
Separately, scientists published results showing that pairing twisted layers of graphene with a synthetic diamond material creates a new mechanism for controlling superconductivity — switching it on and off in a way not previously demonstrated. Moiré materials (created by stacking and rotating 2D layers) have been a fertile area of quantum materials research since 2018; this result adds another tunable degree of freedom to the toolbox.
Security Watch
Quantum sensor breaks zeptojoule barrier — with dark matter implications
Researchers built an ultra-sensitive sensor capable of detecting energy below one zeptojoule (10⁻²¹ joules), using superconducting materials that respond to even the most minute temperature changes. Beyond quantum computing calibration, the sensitivity level opens the door to detecting axions and other dark matter candidates — a scientific use case that is increasingly motivating quantum sensor investment.
