OpenQASM 3: A broader and deeper quantum assembly language

Quantum assembly languages are machine-independent languages that traditionally describe quantum computation in the circuit model. Open quantum assembly language (OpenQASM 2) was proposed as an imperative programming language for quantum circuits based on earlier QASM dialects. In principle, any quantum computation could be described using OpenQASM 2, but there is a need to describe a broader set of circuits beyond the language of qubits and gates. By examining interactive use cases, we recognize two different timescales of quantum-classical interactions: real-time classical computations that must be performed within the coherence times of the qubits, and near-time computations with less stringent timing. Since the near-time domain is adequately described by existing programming frameworks, we choose in OpenQASM 3 to focus on the real-time domain, which must be more tightly coupled to the execution of quantum operations. We add support for arbitrary control flow as well as calling external classical functions. In addition, we recognize the need to describe circuits at multiple levels of specificity, and therefore we extend the language to include timing, pulse control, and gate modifiers. These new language features create a multi-level intermediate representation for circuit development and optimization, as well as control sequence implementation for calibration, characterization, and error mitigation.

Physicists demonstrate a quantum system where the “arrow of time” can be reversed, meaning processes can evolve forward and backward with near-perfect control. The work shows that at quantum scale, time symmetry can be engineered using precise state manipulation.

Quantum Physics Flips Time’s Arrow With Perfect Reversibility

Can diffusion truly be reversed, atom by atom, with perfect accuracy? Experiments now demonstrate 100% time reversal of quantum diffusion in controlled systems, a feat impossible in classical physics due to inevitable error accumulation. This resolves a 150-year-old debate, offering a new quantum lens to examine the foundations of irreversibility.

Quantum Computers Gain Resilience Against Hardware Flaws With New Code Repairs

Previously, unavoidable damage to qubits necessitated disabling surrounding components, wasting valuable computational resources. Now, a new scheme allows colour codes to maintain functionality even with defects by intelligently reusing neighbouring ancilla qubits and employing iSWAP gates. This adaptive deformation reduces logical error rates and supports complex operations without sacrificing qubit density.
