Quick Recap
Welcome to 2021! 2020 was potentially one of the biggest years for Quantum Computing. The hype is real but also, apparently the light at the end of the tunnel.
We conclude the year with additional comments on the quantum supremacy and a paper that could achieve similar results for femion sampling. In terms of news most of us were enjoying some deserved holidays, so not much happened. But we already see movement that will show breakthroughs during Q1. Stay tunned!

Hype VS Reality: Sometimes we see articles like this one:
Quantum computers could crack bitcoin encryption by 2022
While the basis for the article are not that far off, what is completely wrong is the time estimations (according to the majority of scientists and researchers)
Take this answer and apply it to most fancy articles out there claiming useful advantage / supremacy for 2021:
Now, on the bright side, to get there we need more research, more work and more money both on the hardware and the software side. This is how we ended the year (disclosed operations)

The Summary of the Week
Q&A session with Scott Aaronson on Quantum Supremacy with Boson Sampling | QWorld
Scott Aaronson, the inventor of Boson Sampling, perhaps the best-known scientist in quantum computing and complexity theory, and also the author of the popular blog “Shtetl-Optimized.” In this in-depth Q&A session, Scott addressed the burning questions around the latest demonstration of quantum supremacy using an optical quantum computer. It is a must see for those who want to get a glimpse into the logic of academic research that drives the technology behind quantum computing. The full recording contains questions from the moderators and the participants, including Chaoyang Lu who was one of the leaders of the amazing new experimental demonstration.

Important milestone in the creation of a quantum computer
One of the key features of the devices is the two-dimensional array of quantum dots. Or more precisely, a two by two lattice of quantum dots. "What we have shown is that we can realize single electron control in every single one of these quantum dots.

Paper: Fermion Sampling: a robust quantum computational advantage scheme using fermionic linear optics and magic input states
Fermionic Linear Optics (FLO) is a restricted model of quantum computation which in its original form is known to be efficiently classically simulable. We show that, when initialized with suitable input states, FLO circuits can be used to demonstrate quantum computational advantage with strong hardness guarantees. Based on this, we propose a quantum advantage scheme which is a fermionic analogue of Boson Sampling: Fermion Sampling with magic input states.
We consider in parallel two classes of circuits: particle-number conserving (passive) FLO and active FLO that preserves only fermionic parity and is closely related to Matchgate circuits introduced by Valiant. Mathematically, these classes of circuits can be understood as fermionic representations of the Lie groups U(d) and SO(2d). This observation allows us to prove our main technical results. We first show anticoncentration for probabilities in random FLO circuits of both kind. Moreover, we prove robust average-case hardness of computation of probabilities. To achieve this, we adapt the worst-to-average-case reduction based on Cayley transform, introduced recently by Movassagh, to representations of low-dimensional Lie groups. Taken together, these findings provide hardness guarantees comparable to the paradigm of Random Circuit Sampling.
