Pasqal
Pasqal is a French pioneer in neutral-atom quantum computing, building large, reconfigurable arrays of laser‑trapped Rydberg atoms and delivering them as on‑prem accelerators for HPC centers and industrial labs. Unlike many peers that separate “today’s NISQ” from “tomorrow’s FTQC,” Pasqal’s strategy is explicitly continuous: ship useful analog/digital processors now, and upgrade the same platform - via photonic‑integrated control, higher fidelities, and modular scaling - into…

Nord Quantique
Nord Quantique is a Canadian quantum computing startup (founded in 2020 in Sherbrooke, Quebec) focused on building fault-tolerant quantum computers through innovative hardware design. The company’s mission centers on overcoming the main bottleneck in quantum computing - quantum error correction - by integrating error resilience directly into the hardware architecture. Unlike conventional approaches that require large numbers of physical qubits to encode a single logical…

Microsoft
Microsoft’s quantum program is defined by a long‑bet on topological qubits - Majorana‑based devices designed to suppress errors at the hardware level - paired with a near-term, market-facing push through Azure Quantum. Publicly, Microsoft frames its roadmap in three phases: Foundational (prove and control Majorana modes), Resilient (demonstrate error-corrected logical qubits on a small system), and Scale (manufacture at CMOS-like volumes to reach millions of…

IQM
IQM Quantum Computers is a Finland‑based hardware company building superconducting (transmon) quantum processors with a distinctly European strategy: deliver on‑premises systems tightly integrated with high‑performance computing (HPC) centers while co-designing architectures for error correction and, ultimately, fault tolerance. Rather than focus on cloud-only access or headline qubit counts, IQM emphasizes deployable machines, open low-level control for researchers, and chip topologies tailored to quantum error-correcting codes.…

IonQ
IonQ is a publicly traded leader in trapped‑ion quantum computing whose strategy is to reach useful fault tolerance with fewer physical qubits by maximizing fidelity, connectivity, and modularity. Rather than racing raw qubit counts in noisy regimes, IonQ’s thesis is that very clean ions (identical atomic qubits with long coherence and native all-to-all coupling) can slash error‑correction overhead and bring logical qubits online earlier. That…

Intel
Intel’s quantum computing program has carved a distinctive path, marrying cutting-edge quantum research with the might of advanced silicon manufacturing. Over the past several years, Intel progressed from superconducting qubit test chips (17 and 49 qubits) to a focus on silicon spin qubits, culminating in the 12-qubit Tunnel Falls chip in 2023. Alongside qubit chips, Intel engineered a unique cryo-control architecture: the Horse Ridge I/II…

Infleqtion
Infleqtion (formerly known as ColdQuanta) is a leading quantum technology company focused on gate-based quantum computing built on neutral atoms. By leveraging optically trapped atomic qubits, Infleqtion aims to deliver scalable, high-fidelity quantum processors with a clear path toward fault-tolerance and commercial utility. The company’s approach emphasizes large 2D qubit arrays and Rydberg-mediated entangling gates, achieving record gate fidelities and integrating advanced software control to…

Aegiq
Alice & Bob is a Paris-based quantum computing startup (founded in Feb 2020 by Dr. Théau Peronnin and Dr. Raphaël Lescanne) focused on building a universal, fault-tolerant quantum computer using a novel “cat qubit” architecture. The company’s approach leverages superconducting cat qubits, quantum bits that are inherently protected from certain errors, to drastically reduce the overhead for error correction. Backed by substantial funding and scientific…
