Commercialising Quantum – May 17th-19th 2022
As quantum edges closer to becoming mainstream, we are excited to partner with The Economist on their upcoming event, "Commercialising Quantum". The inaugural event will feature a line-up of 100+ speakers, including c-suite from Sanofi, Moderna, Schneider Electric, E.ON, Pfizer and General Motors as well as senior leadership from UK NCSC, Gulf Bank, Google, European Commission and University of California. Attend virtually or in-person in London this May for three days of informative, inspiring, and educational content about the near-term scope of quantum advantage. Expect an unrivalled mix of accessible insights and more technical deep dives that will help you distinguish hype from reality. Register now to secure your place.
Quick Recap
Well, I don’t even know where to start. This week has been packed with amazing published papers and demonstrations. Not just because of the APS March Meeting that puts together some of the best Quantum scientists of the world, but also from the industry announcements. Of course we are talking about Majorana Fermions, the elusive promised land of quantum hardware and error correction codes that will pave the way for our logical qubits. A “fridge to go” for your qubit delivery and a great updated investment map by Qureca. Read on, lots to unpack!
If you are in Madrid, Spain, make sure you attend the Futurizable event on Quantum. Some of the best startups in the country will be there.

Finally, how does a Quantum Computer work? This video from Scientific American does a very good job, so you have materials when you have to explain your friends what on earth you are doing :)
The Quote of the Week
"If you have a theory, you must try to explain what's good and what's bad about it equally. In science, you learn a kind of standard integrity and honesty."

From ‘chandeliers’ to entangled qubits, here’s what happens inside a quantum computer
If the words ‘quantum’ and ‘computing’ seem complicated enough without smushing them together, fear not! This animated explainer will teach you how to build a quantum computer from the qubit up – or, at very least, help you grasp the basics. With nifty animated sequences to explore how quantum computing leverages quantum science, the video covers the broad strokes of the emerging technology, including its potential to revolutionise computing as we know it, and its current limitations.

Quantum Market Gains Commercial Ground: Omdia
Quantum computing is moving beyond the hype to offer practical solutions for several sectors, according to the Top Digital Transformation Trends 2022 report by Omdia research.
This new momentum is being led by a range of technological achievements and predicted growth in investment during 2022. Other contributing factors are an increased focus on near-term use cases and pilot programs and expanding partnerships between research centers or centers of excellence and quantum computing hardware and software vendors.

How this S’pore startup is streamlining coding so regular programmers can also quantum code
You’ve probably heard of quantum mechanics somewhere before — on a television show, on the news, or anywhere really — though we mostly hear it in some abstract scientific context, that’s far removed from the everyday lives of common people.

Paper: Quantum Amplitude Interpolation
In this paper we present a method for representing continuous signals with high precision by interpolating quantum state amplitudes. The method is inspired by the Nyquist-Shannon sampling theorem, which links continuous and discrete time signals.
This method extends our previous method of computing generalized inner products from integer-valued functions to real-valued functions.

What to Expect for a Datacentre or Cloud in Quantum Computing?
Quantum computing is a rapidly-emerging technology that harnesses the laws of quantum mechanics to solve problems too complex for classical computers. Quantum computing remains outside of the traditional landscape when it comes to the datacentre.

Paper: Variational quantum amplitude estimation
We propose to perform amplitude estimation with the help of constant-depth quantum circuits that variationally approximate states during amplitude amplification. In the context of Monte Carlo (MC) integration, we numerically show that shallow circuits can accurately approximate many amplitude amplification steps. We combine the variational approach with maximum likelihood amplitude estimation [Y. Suzuki et al., Quantum Inf. Process. 19, 75 (2020)] in variational quantum amplitude estimation (VQAE). VQAE typically has larger computational requirements than classical MC sampling. To reduce the variational cost, we propose adaptive VQAE and numerically show in 6 to 12 qubit simulations that it can outperform classical MC sampling.

Paper: Quantum Error Mitigation as a Universal Error Reduction Technique: Applications from the NISQ to the Fault-Tolerant Quantum Computing Eras
In the early years of fault-tolerant quantum computing (FTQC), it is expected that the available code distance and the number of magic states will be restricted due to the limited scalability of quantum devices and the insufficient computational power of classical decoding units. Here, we integrate quantum error correction and quantum error mitigation into an efficient FTQC architecture that effectively increases the code distance and T-gate count at the cost of constant sampling overheads in a wide range of quantum computing regimes

Derivative Pricing using Quantum Computers
2019 saw the birth of one of the all-time greats in the history of financial derivatives: Keith Patrick Gill. You might recognize him by one of his pseudonyms, either Roaring Kitty or DFV. In mid 2019, Gill began buying a derivative called an American call option — a contract that gives the owner the right to buy an asset at a fixed price, called the strike price, before a set date (the expiration date). More specifically, Gill began buying call options on GameStop (GME) shares. By trading in these contracts, Gill was able to turn an initial investment of about fifty thousand dollars into nearly fifty million dollars in just over a year! This remarkable anecdote naturally raises the questions: what is the price of these contracts, and how does one determine these prices?
