QpiAI-Indus
QpiAI-Indus is a superconducting circuits quantum computer operated by QpiAI in India. It has 25 physical qubits. It ranks 38 of 53 superconducting machines in this table by physical qubit count. 6 sourced specs are in the spec sheet. 2 published benchmark or milestone records are listed below, each marked by who measured it.
Also known as QpiAI Indus, Indus Quantum Computer
Released on World Quantum Day, 14 April 2025, as India's first full-stack quantum computing platform under the National Quantum Mission; India's Department of Science and Technology is a shareholder of QpiAI. CEO Nagendra Nagaraja quoted T1 of 30 microseconds and T2 of 25 microseconds in May 2025, expected to reach 100 microseconds. QpiAI describes a Gen-1 system with a colocated HPC data center and a roadmap to 128 NISQ qubits and 100 logical qubits by 2030. The hardware's physical site is not stated in the sources consulted.
Spec sheet
Technical details as the builder or a paper states them, each with its own source. A blank is a fact we could not source, not a zero. Fidelity and coherence figures are in the benchmark table below.

Published benchmark figures
These are numbers the builder or a paper reports for this machine, not results from a common test. The basis column says who measured them. What the metrics mean and why they are not comparable across technologies.
| Metric | Value | Measured | Basis | Note | Source |
