Jakub Czartowski, Karol Życzkowski, and Daniel Braun,

Quantum 8, 1341 (2024).

We propose an analogue of $\text{SU}(1,1)$ interferometry to measure rotation of a spin by using two-spin squeezed states. Attainability of the Heisenberg limit for the estimation of the rotat…

Antonio Anna Mele,

Quantum 8, 1340 (2024).

The Haar measure plays a vital role in quantum information, but its study often requires a deep understanding of representation theory, posing a challenge for beginners. This tutorial aims t…

Balázs Pozsgay and Ian M. Wanless,

Quantum 8, 1339 (2024).

Absolutely maximally entangled (AME) states of $k$ qudits (also known as perfect tensors) are quantum states that have maximal entanglement for all possible bipartitions of the sites/parties.…

Jerzy Paczos, Kacper Dębski, Piotr T. Grochowski, Alexander R. H. Smith, and Andrzej Dragan,

Quantum 8, 1338 (2024).

According to relativity, the reading of an ideal clock is interpreted as the elapsed proper time along its classical trajectory through spacetime. In contrast, quantum theory allows the asso…

Louis Paletta, Anthony Leverrier, Alain Sarlette, Mazyar Mirrahimi, and Christophe Vuillot,

Quantum 8, 1337 (2024).

Between NISQ (noisy intermediate scale quantum) approaches without any proof of robust quantum advantage and fully fault-tolerant quantum computation, we propose a scheme to achieve a provab…

Karen V. Hovhannisyan and Alberto Imparato,

Quantum 8, 1336 (2024).

Characterizing fluctuations of work in coherent quantum systems is notoriously problematic. Here we reveal the ultimate source of the problem by proving that ($\mathfrak{A}$) energy conservati…

Hui Wang, Flaminia Giacomini, Franco Nori, and Miles P. Blencowe,

Quantum 8, 1335 (2024).

In physics, it is crucial to identify operational measurement procedures to give physical meaning to abstract quantities. There has been significant effort to define time operationally using…

Julien du Crest, Francisco Garcia-Herrero, Mehdi Mhalla, Valentin Savin, and Javier Valls,

Quantum 8, 1334 (2024).

The inherent degeneracy of quantum low-density parity-check codes poses a challenge to their decoding, as it significantly degrades the error-correction performance of classical message-pass…

Victor Barizien, Pavel Sekatski, and Jean-Daniel Bancal,

Quantum 8, 1333 (2024).

Bell inequalities play a key role in certifying quantum properties for device-independent quantum information protocols. It is still a major challenge, however, to devise Bell inequalities t…

Edwin Peter Lobo, Jef Pauwels, and Stefano Pironio,

Quantum 8, 1332 (2024).

Losses in the transmission channel, which increase with distance, pose a major obstacle to photonics demonstrations of quantum nonlocality and its applications. Recently, Chaturvedi, Viola,…

Yifan Jia and Angela Capel,

Quantum 8, 1331 (2024).

Quantum Wielandt's inequality gives an optimal upper bound on the minimal length $k$ such that length-$k$ products of elements in a generating system span $M_n(\mathbb{C})$. It is conjectured that…

Andrea Coladangelo, Christian Majenz, and Alexander Poremba,

Quantum 8, 1330 (2024).

Copy-protection allows a software distributor to encode a program in such a way that it can be evaluated on any input, yet it cannot be "pirated" – a notion that is impossible to achieve in…

Priya J. Nadkarni, Praveen Jayakumar, Arpit Behera, and Shayan Srinivasa Garani,

Quantum 8, 1329 (2024).

We present the construction of standard entanglement-assisted (EA) qubit Reed-Muller (RM) codes and their tensor product variants from classical RM codes. We show that the EA RM codes obtain…

Philip Taranto, Marco Túlio Quintino, Mio Murao, and Simon Milz,

Quantum 8, 1328 (2024).

Memory is the fundamental form of temporal complexity: when present but uncontrollable, it manifests as non-Markovian noise; conversely, if controllable, memory can be a powerful resource fo…

Manuel G. Algaba, P. V. Sriluckshmy, Martin Leib, and Fedor Šimkovic IV,

Quantum 8, 1327 (2024).

We present a general strategy for mapping fermionic systems to quantum hardware with square qubit connectivity which yields low-depth quantum circuits, counted in the number of native two-qu…
