IBM ibmq_manila

IBM · Apache-2.0 last capture 2024-05-27

ibmq_manila is a 5-qubit IBM quantum computer, with records from 2021 to 2024.

On its latest calibration (27 May 2024), a typical two-qubit operation failed about 1 in 99, better than 45% of the 65 other devices in this record.

The newest record is from 27 May 2024, so the machine may since have been upgraded or retired.

Best 2Q fidelity
IBM · Apache-2.0
0.994304
fails about 1 in 180

Success rate of the chip's single best pair of qubits. The best pair flatters the chip; the typical one matters more.

Median 2Q error
IBM · Apache-2.0
0.0100909
fails about 1 in 99

How often a typical two-qubit operation on this chip fails, from the vendor's own calibration.

Better than 45% of 65 other devices with this measurement
Measured 2024-05-27
Median T1 (µs)
IBM · Apache-2.0
144.67

How long a typical qubit holds its state before it decays, in microseconds. Longer leaves more time to compute.

Better than 67% of 67 other devices with this measurement
Measured 2024-05-27
Median T2 (µs)
IBM · Apache-2.0
54.361

How long a typical qubit keeps its delicate quantum phase, in microseconds.

Better than 15% of 67 other devices with this measurement
Measured 2024-05-27
Median readout error
IBM · Apache-2.0
0.0219
fails about 1 in 46

How often reading a typical qubit's value at the end gives the wrong answer.
