Fusion-based Quantum Computing 1: Building Blocks

In January of 2021, a bunch of people from Palo-Alto-based quantum startup PsiQuantum posted a paper on the arXiv introducing “fusion-based quantum computation” (FBQC), a brand new quantum computing paradigm and a variant of measurement-based quantum computation (MBQC). This is exciting for several reasons: the scheme is a contender for scalable, fault-tolerant quantum computation and it offers several interestingContinue reading “Fusion-based Quantum Computing 1: Building Blocks”

What on Earth is counterdiabatic driving? (Or: the waiter and the glass of wine (water) example that’s been done to death)

Rambling Pre-Amble So I’m rubbish at writing blogs. This is something I’ve now truly proven to myself. Not for lack of trying! In any case, here’s a new entry I’d like to thank the amazing folks at the Quantum Aviary blog for. They gave me the push needed to put something together about the sortsContinue reading “What on Earth is counterdiabatic driving?

What is a Quantum Algorithm? (Part 2: “It” from “Qubit”)

I’ll begin this post with and addendum to the previous part of this series: originally I began this with the intent to sum up (in abstraction) how I understand the concept of quantum algorithms in a fairly practical way. This is still ultimately the goal, but as the previous post grew and my reading materialContinue reading “What is a Quantum Algorithm? (Part 2: “It” from “Qubit”)”

What is a Quantum Algorithm? (Part 1: The Rant about Information)

Here’s a fun, easy topic to start off with. I would like to stress that I do intend to try and make this as accessible as I possibly can. I am by no means a great science communicator, nor one of those absolute genius researchers that I keep running into who seem to understand topicsContinue reading “What is a Quantum Algorithm?
