The Week in Quantum Computing - March 27th
Issue #131
The Week in Quantum Computing. Brought to you by Sergio Gago (@piratecto).
Quick Recap
StrangeWorks finalizes their series A for $24M during a full week of AI developments. IBM announces they will install the third quantum computer in Spain, specificially in the Basque Country (if you ask me, another example of everyone trying to go their own way instead of joining forces). Nvidia had a big week during their conference where they announced several upgrades in cuQuantum, as well as DGX, their GPU accelerated system with big initial partnerships. They also want to improve their litography processes, and for that they have release a platform called “CuLitho” (Yes, if you speak spanish you will be cracking now). This shows how the company is doubling down in Quantum, specifically in the early stages during NISQ. IQM from Finland launches their free “academy” in the hopes of increasing market share, and a very good article from Q. Zeitgeist with 10 free resources to spend your Easter in quantum peace. D-wave is the second company in the industry with a delisting warning trading today at $0,51. Pasqal has created a new platform to get developers more acquianted with neutral atoms (pesky things they are), (the atoms, not the company).
An finally, the elephant in the room. Does Grover’s algorithm provide advantage or not? As you may know, Grover’s algorithm is one of the few that provides theoretical speed up over its classical counterparts and a building block for much of what we do today in Quantum. However a paper published this week (Grover's Algorithm Offers No Quantum Advantage by Stoudenmire and Xavier Waintal) has caused much turmoil in the industry. Almost a civil war between complexity theorists and physicists. In the paper they try to demonstrate that Grover shows no quantum advantage due to the needs of the oracle and that they can achieve a better result using tensor networks. Of course the community took it seriously.
But if you are short on time, this is the thread you have to read.
And if you want to go deeper, refer to Aaronson posts I added below, that summarizes everything. In general, yet another quantum civil war going on. What a time to be alive.
Next Conferences
The global Quantum.Tech summit is headed to Singapore! Being a global hub in the region with a vibrant tech-transfer ecosystem and world class community of researchers, this will be perfect platform to get an unbiased view on where quantum technology in APAC is headed.
Meet me in Boston on April 25th and 26th for two things: Talking about quantum in the finance industry and a private, invite only session for banks, insurance companies and asset managers. If you want your organization to take the leap on what is next in quantum, you can’t miss that session.

Paper Grover's Algorithm Offers No Quantum Advantage
Grover's algorithm is one of the primary algorithms offered as evidence that quantum computers can provide an advantage over classical computers. It involves an "oracle" (external quantum subroutine) which must be specified for a given application and whose internal structure is not part of the formal scaling of the quantum speedup guaranteed by the algorithm. Grover's algorithm also requires exponentially many steps to succeed, raising the question of its implementation on near-term, non-error-corrected hardware and indeed even on error-corrected quantum computers. In this work, we construct a quantum inspired algorithm, executable on a classical computer, that performs Grover's task in a linear number of call to the oracle - an exponentially smaller number than Grover's algorithm - and demonstrate this algorithm explicitly for boolean satisfiability problems (3-SAT). Our finding implies that there is no a priori theoretical quantum speedup associated with Grover's algorithm. We critically examine the possibility of a practical speedup, a possibility that depends on the nature of the quantum circuit associated with the oracle. We argue that the unfavorable scaling of the success probability of Grover's algorithm, which in the presence of noise decays as the exponential of the exponential of the number of qubits, makes a practical speedup unrealistic even under extremely optimistic assumptions on both hardware quality and availability.

Does Grover’s algorithm offer a quantum advantage?
(Aaronson updated several times his post, including an answer to Xavier Waintal, one of the paper’s authors.
In Of course Grover’s algorithm offers a quantum advantage! […] the authors assume you’re given, not merely an oracle for f, but the actual circuit to compute f. They then use that circuit in a non-oracular way to extract the marked item. In which case, I’d prefer to say that they’ve actually solved the Grover problem with zero queries—simply because they’ve entirely left the black-box setting where Grover’s algorithm is normally formulated!
