Now in Quantum: by Yifan Hong, David T. Stephen, and Aaron J. Friedman https://doi.org/10.22331/q-2024-10-10-1499


Yifan Hong, David T. Stephen, and Aaron J. Friedman, Quantum 8, 1499 (2024). We constrain a broad class of teleportation protocols using insights from locality. In the “standard” teleportation protocols we consider, all outcome-dependent unitaries are Pauli operators conditioned on linear functions of the measurement outcomes. We find that all such protocols involve preparing a “resource state” exhibiting symmetry-protected topological (SPT) order with Abelian protecting symmetry $\mathcal{G}_{k}= (\mathbb{Z}_2 \times \mathbb{Z}_2)^k$. The $k$ logical states are teleported between the edges of the chain by measuring the corresponding $2k$ string order parameters in the bulk and applying outcome-dependent Paulis. Hence, this single class of nontrivial SPT states is both necessary and sufficient for the standard teleportation of $k$ qubits. We illustrate this result with several examples, including the cluster state, variants thereof, and a nonstabilizer hypergraph state.

Accidental Discovery in the Lab

The discovery happened unexpectedly during research on warty comb jellies (Mnemiopsis leidyi), also known as sea walnuts, in a lab at the University of Exeter. Researchers noticed that one jelly was missing from a tank, only to realize that a larger jelly was actually two individuals fused together. This accidental fusion occurred when the jellies sustained minor injuries. Excited by the finding, study lead author Kei Jokura immediately shared the discovery with other lab members.

The team then tested whether this fusion could be replicated. They injured 20 comb jellies by removing small sections of their bodies and placed them near each other. Out of the 20, nine pairs fused completely, typically within 24 hours. The merging process also affected their nervous systems, which synchronized rapidly. Researchers observed that the fused individuals reacted as one when poked, indicating a full integration of their neural functions.

Taking aspirin regularly cuts the risk of developing pancreatic cancer by 40% in people with diabetes and by 20% in the general population, according to research.

The PLANETS cancer charity funded the study, which it said has made a “significant finding” for the treatment of what is “one of the worst” cancers because of its poor survival rate.

Researchers at University Hospital Southampton and the University of Southampton studied almost 10,000 people from the UK Biobank – a cohort of 500,000 people aged between 37 and 73 recruited between 2006 and 2010.

TSMC’s 3nm process is set to receive massive adoption in the AI sector, as Intel, NVIDIA, & AMD plan on utilizing the technology in their next-gen accelerators.

TSMC’s 3nm Process Is demanding in The Tech Markets As It Manages To Capture Most Of The Market Share: NVIDIA Rubin, AMD MI355X & Intel’s Falcon Shores For Next-Gen AI Markets

The Taiwan giant’s next node is said to be highly demanding in the markets, mainly because mainstream tech companies have revolved their upcoming product portfolios around the process. Notable examples include Apple for its upcoming A19 Pro chip, MediaTek’s Dimensity 9,400, and even Google’s Tensor G5. And now, it looks like we have clarity on the adoption of TSMC’s 3nm by the AI tech giants, such as NVIDIA and AMD out there, with a new report by Ctee now showing us where the process is expected to be integrated when it comes to AI portfolios.
