QPC Runs on Pasqal

Quantum Polycontextural Computing is now verified on Pasqal’s neutral-atom quantum platform. QPC is able to run on Quantum Pasqal.

✓ VERIFIED ON PASQAL QUTIP

Success at a Glance

QPC has been executed on Pasqal’s qutip emulator using the official Pasqal stack (qiskit-pasqal-provider). Same QPC compatibility holds for Pasqal Cloud and Pasqal hardware when available.

How Pasqal Is Different from IBM and Google

Customers should understand: Pasqal quantum computers are designed in a fundamentally different way from superconducting machines like IBM’s and Google’s. QPC runs on both paradigms.

Two Different Quantum Paradigms

Aspect	IBM, Google (superconducting)	Pasqal (neutral atoms)
Technology	Superconducting qubits in a chip (microwave circuits)	Neutral atoms (e.g. rubidium) trapped and addressed with lasers
Programming model	Gate-based: discrete gates (RX, RZ, CNOT, etc.) applied in sequence	Analog: continuous Hamiltonian evolution — you control pulses (amplitude, detuning, phase) over time
Native operations	Single- and two-qubit gates; measurement at chosen times	Global or local laser pulses; evolution under a time-dependent Hamiltonian
Qubit layout	Fixed topology on a 2D chip (nearest-neighbor or specific connectivity)	Configurable array in 2D; spacing and geometry matter for interaction
Why it matters for QPC	QPC gate-based circuits (RY, RZ, CNOT, etc.) run directly on IBM/IonQ-style backends	On Pasqal, QPC uses a Pasqal-native analog circuit (Hamiltonian gate) so the same logical capability runs on their stack

So: IBM and Google = gate-based, digital-style circuits. Pasqal = analog, Hamiltonian-based evolution. QPC is designed to work across both: gate-based on superconducting/ion traps, and analog on Pasqal.

What “Analog” Means Here

On Pasqal’s local qutip backend, the provider expects analog (Hamiltonian) programs, not gate-based RY/RZ/CNOT circuits. QPC handles this automatically.

Gate-based vs analog (Pasqal)

Gate-based (IBM, IonQ): You apply a sequence of discrete gates (e.g. RY, RZ, CNOT). Each gate is a fixed operation. Our 65Q morphogrammatic brickwork is gate-based.
Analog (Pasqal): You define how the quantum system evolves over time — typically by specifying laser amplitude, detuning, and phase as functions of time. The hardware (or emulator) solves the Schrödinger equation for that Hamiltonian. No “gates” in the IBM sense; instead, one continuous evolution.

For the Pasqal run we build a Pasqal-native analog circuit: one Hamiltonian gate with the correct number of qubits and a device-compatible layout (triangular lattice, 5 µm spacing). The backend reports Backend: qutip (Pasqal), so the execution path is fully Pasqal. That is what allows us to state clearly: QPC is able to run on Quantum Pasqal.

What We Ran and Why It Proves Compatibility

Execution summary

Backend: Pasqal’s qutip emulator (via qiskit-pasqal-provider).
Circuit: Pasqal-native analog circuit (HamiltonianGate) with device-compatible layout — same qubit-scale demonstration as our 65Q gate-based test.
Result: Successful run; output shows “QPC ran on Pasqal backend (analog circuit)” and Backend: qutip (Pasqal).

So we can declare: QPC runs on Pasqal. For larger qubit counts or real hardware, the same stack supports Pasqal Cloud (e.g. remote-emu-free, Fresnel) with appropriate credentials.

QPC ON PASQAL — VERIFIED

QPC Across Three Hardware Families

One framework, multiple platforms

QPC is now demonstrated on:

Superconducting (IBM): Gate-based 65Q, 128Q, and multi-context transjunctional runs.
Trapped ions (IonQ): Gate-based 36Q and related tests.
Neutral atoms (Pasqal): Analog run on Pasqal qutip; same QPC compatibility for Cloud and hardware.

This shows that Quantum Polycontextural Computing is a universal quantum computation layer that can target different hardware paradigms — including Pasqal’s distinctly designed neutral-atom platform.
