Pulse Control
Manipulate quantum processors at the physical level.
Low-level programming control
Limited control over hardware physics
Pre-calibrated gates act as a layer of abstraction, limiting direct control over qubit interactions and the creation of custom low-level operations. Quantum physicists often need to manipulate the underlying physics of qubits to optimise performance and explore new operations.
Hardware-agnostic pulse shaping
Triple Alpha gives users direct control over the pulses sent to the quantum processor, enabling them to shape pulses and interact with the underlying physics. Developers can use pulse shaping to reduce errors, improve gate fidelity, and optimise hardware performance, and Triple Alpha’s hardware-agnostic approach provides them with consistent, low-level control across different quantum processors.
Improved fidelity
By tailoring pulses to specific hardware conditions, developers can achieve more precise control over a quantum system, reducing errors and increasing the accuracy and reliability of quantum gate operations beyond what standard gate calibrations alone can offer. Improved precision is especially important at scale: errors that are insignificant over short sequences accumulate over long computations, meaning a seemingly small improvement rate, such as 0.2%, gives drastically different results when running a circuit 10 times vs. 10,000 times.
Hardware optimisation
Pulse control supports detailed characterisation, calibration, and fine-tuning of hardware, all tailored to the specific behaviour and imperfections of each device. This optimisation enables more efficient and reliable quantum computations, adapted to each processor’s unique characteristics. For example, pulse-level control allows ZZ crosstalk to be characterised and actively cancelled through techniques such as echoing, directly translating detailed hardware calibration data into higher-fidelity quantum operations.
Direct customisation
Pulse control lets developers define the actual signals sent to qubits, providing fine-grained control over quantum operations. Combined with Triple Alpha’s qubit-pinning capability, it allows precise targeting of specific qubits on the processor, offering full low-level control.
