Bio

Dawei Ding’s research is in the field of theoretical quantum information science, in particular the intersection of quantum computing theory and device physics. At present, his main research directions include:

1. “Quantum computing at the physical layer.” Currently, theoretical quantum computing takes a top-down approach, generalizing well-known classical concepts to the quantum realm. However, this approach does not take into account physical implementation and can lead to significant problems when put into practice. For example, using the surface code to run Shor’s algorithm to break RSA-2048 requires 20 million physical qubits, a daunting feat for any physical platform. A bottom-up approach can complement the current approach, but the emphasis is instead to start with the low-level device physics. Based on this, a more practical realization of quantum computing can be achieved. This research can be specifically applied to quantum circuit compilation, fault-tolerant quantum computing, etc.
2. “Quantum telepathy.” Although quantum entanglement cannot achieve superluminal communication, it can realize non-classical correlations superluminally. This phenomenon is also known as Bell inequality violation, but this is not just a matter of fundamental physics. It can also have many practical applications, such as distributed computing. Modern classical processors have clock speeds of GHz or higher. At these latencies, even the speed of light delay is significant. Indeed, if two processors are more than 30 cm apart, the speed of light delay already exceeds 1 ns. Hence, operations of different processors are very often space-like separated. To achieve coordinated decision making between such processors, quantum entanglement can provide a mathematically provable advantage.
