RPI IBM Quantum System One
RPI IBM Quantum System One is a superconducting circuits quantum computer operated by Rensselaer Polytechnic Institute in USA. It has 127 physical qubits. It ranks 12 of 43 superconducting machines in this table by physical qubit count. 8 sourced specs are in the spec sheet. No benchmark figures are recorded for it yet.
Also known as Rensselaer IBM Quantum System One
IBM Quantum System One in the Voorhees Computing Center at Rensselaer Polytechnic Institute, billed as the first IBM Quantum System One on a university campus. Installation began in October 2023 and the system was unveiled on 5 April 2024. It uses a 127-qubit Eagle processor. Current upgrade status was not found in the pages 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.
| Spec | Value | Basis | Note | Source |
|---|---|---|---|---|
| Processor | IBM Quantum Eagle r3, 127 qubits | Vendor reported | IBM's release says a 127-qubit Eagle and a July 2024 survey lists backend ibm_rensselaer as Eagle r3 with 127 qubits. | newsroom.ibm.comarxiv.org |
| Qubit type | fixed-frequency transmon qubits | Peer reviewed | A Nature paper describes the 127-qubit Eagle ibm_kyiv as fixed-frequency transmons and a 2024 survey says IBM processors are transmon-based; family-level. | pmc.ncbi.nlm.nih.govarxiv.org |
| Topology | heavy-hex lattice | Peer reviewed | The Nature paper gives heavy-hex connectivity for Eagle and the 2024 survey says Eagle uses a heavy-hexagonal layout; family-level. | pmc.ncbi.nlm.nih.govarxiv.org |
| Max connectivity | 3 | Peer reviewed | The Nature paper says each Eagle qubit has at most three neighbours and the 2024 survey says two or three; family-level. | pmc.ncbi.nlm.nih.govarxiv.org |
| Native gates | ECR, RZ, SX, X, ID | Independent | A July 2024 survey lists these basis gates for ibm_rensselaer and IBM documentation lists ECR as the Eagle two-qubit gate. | arxiv.orgquantum.cloud.ibm.com |
| Two-qubit gate time | 666 ns | Independent | Median ECR duration (665.889 ns) for ibm_rensselaer in a July 2024 snapshot of that survey. | arxiv.org |
| Cooling and environment | dilution refrigerator inside the System One enclosure | Vendor reported | IBM's blog says its quantum processors sit in a dilution refrigerator that reaches 15 to 20 millikelvin; this is an IBM-wide statement, not specific to this unit. | ibm.com |
| Access and pricing | on-premises at the Voorhees Computing Center; dedicated access for RPI researchers, students and partners | Vendor reported | RPI and IBM describe dedicated access for RPI's network and say partner institutions can work with RPI; no price is published. | news.rpi.edunewsroom.ibm.com |
