Density matrix simulator (DM1)
DM1 is an on-demand, high-performance, density matrix simulator. It can simulate circuits of up to 17 qubits.
DM1 has a maximum runtime of 6 hours, a default of 35 concurrent quantum tasks, and a maximum of 50 concurrent quantum tasks.
DM1 results
DM1 can provide the following results, given the specified number of shots:
-
Sample: Shots > 0
-
Expectation: Shots >= 0
-
Variance: Shots >= 0
-
Probability: Shots > 0
-
Reduced density matrix: Shots = 0, up to max 8 qubits
For more information about results, see Result types.
DM1 is always available, it runs your circuits on demand, and it can run multiple circuits in parallel. The runtime scales linearly with the number of operations and exponentially with the number of qubits. The number of shots has a small impact on the runtime. To learn more, see Compare simulators.
