Isentroniq

Isentroniq is a Paris-based quantum hardware startup founded in May 2025 by Paul Magnard (PhD in experimental quantum information processing from ETH Zürich, former lead architect at Alice & Bob) and Théodore Amar (former Bain & Company consultant, ex-head of marketing at Hilti) that develops next-generation wiring infrastructure for superconducting quantum computers to solve the critical cryogenic power and space bottleneck that currently limits scaling beyond a few hundred qubits. In October 2025, Isentroniq raised €7.5 million in pre-seed funding led by Heartcore Capital with participation from OVNI Capital, Kima Ventures, IXCORE Group, Better Angle, EPSL VC, plus support from Bpifrance and France 2030 to industrialize its proprietary dense, near-heatless wiring technology that enables 1,000x more qubits to be integrated into existing dilution refrigerators. The company's breakthrough wiring solution is designed to remove heat, cost, and space constraints inside cryostats and unlock the path to million-qubit systems, with the potential to reduce the price of a million-qubit quantum computer from tens of billions to approximately €50 million while solving the wiring deadlock that has become the primary barrier to scaling superconducting quantum processors as control and readout lines currently add excessive heat and complexity that cap systems at a few hundred qubits.
