Start from a Hamiltonian12Pauli terms, e.g. ZZI:-1, XII:0.5
Hamiltonian time evolutionTime evolution under a Hamiltonian, with its Trotter error.36 qubitsTime-dependent H(t)A Hamiltonian that changes with time — annealing, quenches.10 qubitsDrive it periodicallyDriven periodically: quasi-energies, not energy levels.8 qubitsOpen system: T1, T2, steady stateRelaxation and dephasing acting continuously.6 qubitsWatch the quantum jumpsThe individual jumps, not the average over them.6 qubitsWhat the light looks likeThe spectrum a spectrometer records, and photon statistics.6 qubitsLet the environment set the ratesRates derived from a bath spectrum instead of assumed.6 qubitsTemperature, chaos, thermalizationThermal averages over the whole spectrum.12 qubitsIs it chaotic?Integrable or chaotic, as a number with known references.12 qubitsLook inside an eigenstateHow much entanglement single eigenstates carry.12 qubitsWhat a scattering experiment seesS(k,ω): what a scattering experiment measures.12 qubitsHow fast does information spread?How fast a disturbance spreads — the light cone.12 qubits

Simulation engines
Statevector
Exact unitary evolution. Full visualization — amplitudes and Bloch spheres.
≤ 34 qubits
Matrix product state
Scales with entanglement, not qubit count. Ideal for shallow circuits.
100+ qubits
Stabilizer (Stim)
Tableau simulation for Clifford circuits. Polynomial memory, vast scale.
1000s of qubits
1101001k
qubit reach (log)Chosen per circuit, not per user — a job runs on whichever of these its shape allows.
