Startups quânticas

	Empresa	Modalidade	Status	Abordagem
	IQM	superconducting	private	Europe's largest superconducting startup, selling on-premise systems to research centers and building co-design processors.
	Alice & Bob	superconducting	private	French startup building 'cat qubits'. Superconducting qubits designed to suppress bit-flip errors by construction, aiming to shrink error-correction overhead.
A	Alpine Quantum Technologies	trapped-ion	private	Austrian spin-out from Innsbruck's ion-trapping groups, selling compact rack-mounted trapped-ion systems.
U	Universal Quantum	trapped-ion	private	UK company pursuing large-scale trapped-ion machines linked by electric-field chip-to-chip connections rather than optics.
	QuEra	neutral-atom	private	Boston neutral-atom company from Harvard/MIT research, known for large programmable arrays and error-correction collaborations.
	Pasqal	neutral-atom	private	French neutral-atom company co-founded by a physics Nobel laureate, selling systems to HPC centers.
A	Atom Computing	neutral-atom	private	US neutral-atom company that announced large-array machines and partners with Microsoft on error-corrected demonstrations.
I	Infleqtion	neutral-atom	private	Neutral-atom computing plus a revenue-generating quantum-sensing business (formerly ColdQuanta).
p	planqc	neutral-atom	private	Munich startup from the Max Planck ecosystem building neutral-atom machines for European HPC centers.
	PsiQuantum	photonic	private	The best-funded private quantum company; skipping NISQ entirely to build a million-qubit fault-tolerant photonic machine using semiconductor fabs.
X	Xanadu	photonic	private	Canadian photonic company behind the PennyLane software library and photonic sampling demonstrations.
	Quandela	photonic	private	French photonic company building single-photon sources and cloud-accessible photonic processors.
O	ORCA Computing	photonic	private	UK photonic company using fiber-based memory to make photonic processing practical at room temperature.
D	Diraq	silicon-spin	private	Sydney spin-out commercializing decades of UNSW silicon-qubit research.
Q	Quantum Motion	silicon-spin	private	UK company building silicon spin qubits with standard CMOS processes.
S	Silicon Quantum Computing	silicon-spin	private	Australian company placing individual phosphorus atoms in silicon with atomic precision.
Q	Quobly	silicon-spin	private	French (CEA-Leti spin-off) silicon-spin company leveraging the Grenoble microelectronics ecosystem.
Q	Q-CTRL	software	private	Quantum control and error-suppression software that improves other people's hardware: plus a sensing division.
C	Classiq	software	private	High-level quantum algorithm design: describe the function, synthesize the circuit for any hardware.
	Multiverse Computing	software	private	Spanish company applying quantum and quantum-inspired algorithms (notably tensor networks) to finance and industry: including AI-model compression.
