For students and researchers alike, the field of quantum computing is difficult to approach. The nature of quantum computing runs counter to the intuitive framework applied to most other domains in the computer sciences. Specialized quantum computing systems are not readily available if they exist at...
A key open question in quantum computing is whether quantum algorithms can potentially offer a significant advantage over classical algorithms for tasks of practical interest. Understanding the limits of classical computing in simulating quantum systems
operations. Below we will use gate complexity and the number of operations interchangeably when discussing the scaling of classical algorithms. Although these techniques are not implemented in every quantum chemistry code, we regard them as the main point of comparison to quantum algorithms. We also ...
This thesis presents three results of relevance to the simulation of quantum dynamics on quantum computers. The first is the development of hybridized methods of quantum simulation with Alessandro Roggero and Nathan Wiebe. Conventional methods of quantum simulation, such as qDRIFT, Trotterization, and...
A systematic method for simulating small-scale quantum circuits by use of linear optical devices is presented. It relies on the representation of several quantum bits by a single photon, and on the implementation of universal quantum gates using simple o

simulations of quantum algorithms by adiabatic evolu- tion solving hard instances of satisfiability problems have been carried so far up to 30 qubits [10]. The explosion of entanglement between random cuts in the quantum register was first analyzed in ref. [11]. The adiabatic evolution drive...
“Summit” supercomputer at ORNL. The results were quite staggering then, showing the simulation of the full 53-qubit “Sycamore” circuit on “Summit” would have takenten thousand yearswith the current state of algorithms, but took around 200 seconds on “Sycamore”. That’s not only faster...

intractable problems. Quantum circuit simulation is essential to understanding quantum computation and the development of quantum algorithms. In a quantum circuit, the quantum device is composed ofNqubits, and computations are performed by applying a sequence of quantum gates and measurements to the ...
