Quantacet

Quebec's first dedicated quantum-only VC, founded inside Sherbrooke's DistriQ Quantum Innovation Zone. Backs pre-seed/seed quantum HW, SW, sensing and photonics builders rooted in Québec deep-tech research; portfolio star Nord Quantique reached a US$1.4B valuation in May 2026.

Investment thesis

Quantacet is the first and only quantum-dedicated VC in Québec, founded 2023 in Sherbrooke at the heart of the DistriQ quantum innovation zone. Fund I reached CA$24M: first close CA$20M in November 2023 with the Québec government anchoring CA$10M via Investissement Québec alongside ~20 private LPs, plus a CA$4M commitment in 2024 from the IQ-managed Eureka fund dedicated to pre-seed spin-outs from Québec public research. Cheques CA$500k-1M, lead or co-lead at pre-seed and seed.

Concentrated Québec-rooted portfolio: Nord Quantique (bosonic fault-tolerant superconducting; DARPA QBI Stage B selectee with a path to up to US$300M in Stage C program funding; reached a US$1.4B valuation in its Fidelity-led May 2026 growth round), SBQuantum (quantum magnetometry, seed co-led 2026), Femtum (mid-IR lasers for semiconductor manufacturing, CA$16M Series A 2026), Quminex and SilQ Connect (QV Studio spin-outs), Xatoms (quantum-AI water purification), Phantom Photonics, Quantum Elements (LA, with Québec-anchoring plans) and Irreversible (analog edge-AI chips, an adjacent compute bet).

Co-managed by Partners Martin Laforest, Chloé Archambault and Ghyslain Goulet (CEO of the ACET accelerator, a strategic partner). Quantacet is a co-founding partner of QV Studio, the Sherbrooke quantum venture studio whose companies Quantonation co-invests in (Quminex, SilQ Connect).

Differentiated as the institutional anchor of Québec's quantum corridor: embedded in DistriQ, tightly linked to Université de Sherbrooke's Institut quantique, and the only Canadian quantum-dedicated fund with a sovereign anchor LP.

Anti-thesis

The patterns that trigger a fast no with this fund.

  1. Pure quantum software or algorithm plays with no hardware, photonics, or enabling-tech component, where Quantacet's Sherbrooke and Polytechnique technical edge brings no signal
  2. Late-stage or growth rounds (Series B+): the 20M fund is structured for pre-seed and seed checks, not scaling capital
  3. Non-Canadian deals with zero Quebec footprint, no DistriQ / IQ-Sherbrooke / Polytechnique anchor, and no plan to recruit local talent or use the IBM Quantum hub
  4. Quantum-washed classical startups (AI optimization, HPC) repackaged as quantum without genuine quantum physics IP
  5. Solo founders without a co-investor syndicate (Quantonation, ACET, Investissement Quebec): the fund size requires capital partners to take meaningful positions
