研究领域
丁大威的研究集中在理论量子信息科学领域，特别是量子计算理论跟硬件的交叉点。他现阶段主要的研究方向有两个：
“物理层的量子计算” 量子计算理论目前阶段主要是一个自上而下的方式，从一些从经典计算借来的抽象概念推广到量子。可是这个角度不考虑硬件实现，导致很多理论方案不实用，比如用surface code跑Shor算法来破解RSA加密需要2千万个物理比特。现在所需要的是一个自下而上的角度，可以跟现在的方法配合，可是区别是要先从硬件底层物理作为出发点，然后根据这个来提出一个实现量子计算的理论方案。这种研究具体可应用于量子电路编译，容错量子计算等。
“量子心灵感应” 虽然不能通过量子纠缠实现超光速通讯，量子纠缠可以实现超光速协调。这现象也叫贝尔不等式违反，可是它不仅是一个基础物理现象。它其实可以有很多实际应用，比如分布式计算。现在经典处理器运算可以在1纳秒以下实行操作。跟这么短的时间比较，连光速延迟也会显慢。只要两个处理器间距离超过30厘米，光速延迟已经超过1纳秒了。这种高速运作，没有时间沟通的情况下，如果要实现两个处理器的协调动作的话，量子纠缠可以提供可证明的优势。
