Quantum computing is a rapidly advancing field that offers immense potential for solving complex problems. Traditionally, there are two modes of operation in quantum computing: digital and analog. Each mode has its own advantages and limitations. However, PASQAL, a leading quantum computing company, has introduced a groundbreaking software called Qadence that combines the best elements of both modes to achieve unparalleled efficiency and performance.
In digital mode, quantum circuits are implemented using a series of gates applied to qubits. This mode is universal, meaning it can theoretically solve any problem. However, digital mode requires error correction due to the noisy nature of gates, and it demands a large number of qubits and gates to provide significant quantum advantage.
On the other hand, analog mode introduces a different approach. It allows the qubits to evolve continuously within a register, making it more tolerant of errors. Analog mode can accomplish in a single computational step what digital mode would require in thousands of steps. However, analog mode is not universal and is limited to specific problem types.
PASQAL’s Qadence software disrupts the conventional understanding of quantum computing by introducing Digital Analog Quantum Computing (DACC). This innovative approach enables the use of both digital and analog modes in tandem, harnessing the unique benefits of each.
Qadence, an open-source Python library, configures the qubits into blocks. Quantum gates can be applied to the qubits within a block, and then the blocks are fed into an analog block. This analog block allows the quantum system to evolve continuously in a controlled manner, taking full advantage of analog mode’s error tolerance and efficiency.
To enhance the capabilities of Qadence, PASQAL has integrated it with two other programming libraries: PyQTorch and Pulser. PyQTorch is a fast emulator for digital and digital-analog programs, built on top of the popular PyTorch library. Pulser, on the other hand, is a pulse-level interface specifically designed for programming neutral atom devices.
This novel approach to quantum computing opens up a world of possibilities. By combining the strengths of digital and analog modes, PASQAL’s Qadence software has the potential to revolutionize the field and expedite breakthroughs in various industries such as drug discovery, optimization, and cryptography.
