A universal fault-tolerant quantum computer that can efficiently solve problems such as
integer factorization and unstructured database search requires millions of qubits with low …

We introduce a method to perform imaginary time evolution in a controllable quantum
system using measurements and conditional unitary operations. By performing a sequence …

We show that quantum nondemolition (QND) measurements can be used to realize
measurement-based imaginary-time evolution. In our proposed scheme, repeated weak …

We propose a simple construction of shortcuts to adiabaticity tracking instantaneous
stationary states in classical spin systems without knowing tracked stationary states. In our …

We propose a mean to obtain computationally useful resource states also known as cluster
states, for measurement-based quantum computation, via transitionless quantum driving …

We report that the optical gain and intensity difference squeezing (IDS) of four-wave mixing
can be controlled using an external dressing field in a hot rubidium atomic system. The …

Expanding the benefits of quantum computing to new domains remains a challenging task.
Quantum applications are concentrated in only a few domains, and driven by these few, the …

We consider the explicit construction of resource states for measurement-based quantum
information processing. We concentrate on special-purpose resource states that are capable …

So far, we have described a quantum computer technology that relies on gates and
connecting wires to implement any algorithm. Such a paradigm is sometimes called the …
