MARMOT

The first commercial 19-inch rack-mounted quantum computer

Engineered to fit within two 19-inch rack cabinets, the full system has less than 2m2 footprint. MARMOT operates in a comfortable room temperature environment and consumes less than 2kW of electrical power, ideal for the installation at high-performance computing infrastructures, data-centers or offices.

MARMOT

Our quantum computer features a proven architecture and modularity

The system operates with only a single wall-mounted power plug, eliminating the need for special cooling, vibration insulation, or other typical requirements associated with quantum devices.

The hardware is compatible with the largest ‘out-of-the-box’ software development frameworks such as Qiskit, Cirq, and PennyLane. The standardised interfaces allow you to readily execute your quantum algorithms without any detailed knowledge of the underlying hardware.

The MARMOT system has already been used to investigate quantum benefits in the fields of chemistry, portfolio optimisation, risk analysis, quantum security and decryption.

Designed for stability and reliability

Considering typical gate times on the order of 10 to 100 µs, the quantum memory persists for the equivalent of up to 1000 quantum gate operations, while single-qubit error rates lie below the fault-tolerant threshold.

Long quantum memory lifetime and coherence times
Long quantum memory lifetime and coherence times

All qubit lifetimes T1 from a register of 20 qubits match within one standard deviation and agree with the natural lifetime of the qubit transition T1,nat = (1.165 +/- 0.011) s.

A laser linewidth of less than 1 Hz and highly stable magnetic fields provide us with an excellent T2 time between 0.5-1.2 s.

Low crosstalk and error rates

MARMOT features single-qubit error rates of (3.67+/-0.81)e-4 and average coupling to next-neighbor qubits of 0.6%. These error rates are compatible with fault-tolerant requirements. More

The quantum volume test is an internationally applied benchmark that assesses and describes the computational power of a quantum computer with a single number. The number is sensitive to the size of the quantum register, the quality of the control, and the versatility of controlling quantum information in different locations of the quantum memory.

The low error rates and long coherence times demonstrated with MARMOT and it’s predecessor IBEX, provide confidence that AQT’s quantum computer systems offers long-term solutions that enable error correction routines out of the box. Reduced cross-talk allows end-users to implement algorithms without considerations to know or implement hardware-specific error mitigation techniques.

The MARMOT system contains several quantum components that are designed and built by AQT: PINE SET-UP, BEECH, ROWAN. Those individual products have been used by our customers to realize a world-record of 24-qubit entanglement, perform error correction, and demonstrate the first universal gate-set for logical qubits.
