Adversary lower bounds in the Hamiltonian oracle model

When I switched into quantum computing for my Ph.D. topic, one of the the first research questions that my (former) supervisor, Dr. Richard Cleve, had asked me was whether the adversary method for quantum lower bounds applied in the Hamiltonian oracle model.

The answer is “yes”… » [Expand post] [Permalink]

My depression in Waterloo, part 6: meeting people

As a consequence of being a graduate student in quantum computing, I met several people whose papers I had read in high school and whose writings had influenced my interests. It was very cool, for example, to sit next to Dr. Charles Bennett during a lecture at the Perimeter Institute and to watch him grill the speaker. My supervisor, Dr. Cleve, also introduced me personally to Dr. John Preskill, a meeting which I will describe in another post.

Another person I met through Dr. Cleve was Dr. Michael Nielsen, the co-author with Dr. Isaac Chuang of the standard textbook on quantum computing. Dr. Nielsen is writing a book on the future of science and is interested in the effects of modern communications technologies on scientific research and collaboration, a topic which I had been thinking and writing about since high school. But when I met him, I couldn’t bring myself to discuss it with him.

I have already written about this kind of self-sabotage, of holding myself back… » [Expand post] [Permalink]

My depression in Waterloo, part 5: feeling “unworthy”

The main part of my strategy for overcoming my depression is to identify its triggers and confront each and every one of them by writing about them. Since switching my Ph.D. research topic to quantum computing, almost everything that I encountered every single day as a graduate student in this area has been a trigger of my depression.

The very situation itself was depressing to me, which is in some ways quite irrational. I had told my father when I was in high school that there would be a close collaboration between computer scientists and physicists to study the physics of computation, and now I was a part of this. But in many ways I felt very out of place… » [Expand post] [Permalink]

My depression in Waterloo, part 4: switching into quantum computing

In the first term of my Ph.D., I audited the Quantum Information course taught by Dr. Ashwin Nayak, but did not take it for credit. This was partly because I was so distracted by my predicament, but also because I initially didn’t want the course to appear on my transcript, lest my parents should see it. I was originally just going to sit in on the lectures, but Dr. Nayak convinced me to audit the course, because I had been doing the assignments anyway. And so the course did, in fact, appear on my transcript after all.

During the next several terms, I took some courses to satisfy my degree requirements, while I searched for a way to do research into quantum computing without my parents’ interference. I started to become depressed, because, perhaps unsurprisingly, my parents had begun to attack me for studying bioinformatics. I suppose that the onset of my depression had always only been a matter of time… » [Expand post] [Permalink]
