Self-consistency of the two-point energy measurement protocol
M. Hamed Mohammady
A thermally isolated quantum system undergoes unitary evolution by interacting with an external work source. The two-point energy measurement (TPM) protocol defines the work exchan…
Quantum switch in the gravity of Earth
Natália S. Móller, Bruna Sahdo, Nelson Yokomizo
We introduce a protocol for a quantum switch in the gravitational field of a spherical mass and determine the time interval required for its realization in the gravity of Earth. On…
Finite-Function-Encoding Quantum States
Paul Appel, Alexander J. Heilman, Ezekiel W. Wertz +4
We introduce finite-function-encoding (FFE) states which encode arbitrary -valued logic functions, i.e., multivariate functions over the ring of integers modulo , and investi…
Joint statistics of work and entropy production along quantum trajectories
Harry J. D. Miller, M. Hamed Mohammady, Martí Perarnau-Llobet +1
In thermodynamics, entropy production and work quantify irreversibility and the consumption of useful energy, respectively, when a system is driven out of equilibrium. For quantum…
Fuzzy measurements and coarse graining in quantum many-body systems
Carlos Pineda, David Davalos, Carlos Viviescas +1
Using the quantum map formalism, we provide a framework to construct fuzzy and coarse grained quantum states of many-body systems that account for limitations in the resolution of…
Pathways for entanglement based quantum communication in the face of high noise
Xiao-Min Hu, Chao Zhang, Yu Guo +10
Entanglement based quantum communication offers an increased level of security in practical secret shared key distribution. One of the fundamental principles enabling this security…
Probabilistic storage and retrieval of qubit phase gates
Michal Sedlák, Mário Ziman
Probabilistic storage and retrieval (PSR) of unitary quantum dynamics is possible with exponentially small failure probability with respect to the number of systems used as a quant…
Choice of mutually unbiased bases and outcome labelling affects measurement outcome secrecy
Mirdit Doda, Matej Pivoluska, Martin Plesch
Mutually unbiased bases (MUBs) are a crucial ingredient for many protocols in quantum information processing. Measurements performed in these bases are unbiased to the maximally po…
Thermodynamic uncertainty relation in slowly driven quantum heat engines
Harry J. D. Miller, M. Hamed Mohammady, Martí Perarnau-Llobet +1
Thermodynamic Uncertainty Relations express a trade-off between precision, defined as the noise-to-signal ratio of a generic current, and the amount of associated entropy productio…
Classical Communications with Indefinite Causal Order for completely depolarizing channels
Sk Sazim, Michal Sedlak, Kratveer Singh +1
If two identical copies of a completely depolarizing channel are put into a superposition of their possible causal orders, they can transmit non-zero classical information. Here, w…
Quantum key distribution overcoming extreme noise: simultaneous subspace coding using high-dimensional entanglement
Mirdit Doda, Marcus Huber, Gláucia Murta +3
High-dimensional entanglement promises to increase the information capacity of photons and is now routinely generated exploiting spatio-temporal degrees of freedom of single photon…
Creation of quantum coherence with general measurement processes
Sanuja D. Mohanty, Gautam Sharma, Sk Sazim +2
Quantum measurement not only can destroy coherence but also can create it. Here, we estimate the maximum amount of coherence, one can create under a complete non-selective measurem…
High-Dimensional Pixel Entanglement: Efficient Generation and Certification
Natalia Herrera Valencia, Vatshal Srivastav, Matej Pivoluska +4
Photons offer the potential to carry large amounts of information in their spectral, spatial, and polarisation degrees of freedom. While state-of-the-art classical communication sy…
Non-Local Network Coding in Interference Channels
Jiyoung Yun, Ashutosh Rai, Joonwoo Bae
In a network, a channel introduces correlations to the parties that aim to establish a communication protocol. In this work, we present a framework of non-local network coding by e…
Semi-Device-Independent Random Number Generation with Flexible Assumptions
Matej Pivoluska, Martin Plesch, Máté Farkas +6
Our ability to trust that a random number is truly random is essential for fields as diverse as cryptography and fundamental tests of quantum mechanics. Existing solutions both com…
Experimental creation of Multi-Photon High-Dimensional Layered Quantum States
Xiao-Min Hu, Wen-Bo Xing, Chao Zhang +6
Quantum entanglement is one of the most important resources in quantum information. In recent years, the research of quantum entanglement mainly focused on the increase in the numb…
Pinned QMA: The power of fixing a few qubits in proofs
Daniel Nagaj, Dominik Hangleiter, Jens Eisert +1
What could happen if we pinned a single qubit of a system and fixed it in a particular state? First, we show that this can greatly increase the complexity of static questions -- gr…
Coherence of a driven electron spin qubit actively decoupled from quasi-static noise
Takashi Nakajima, Akito Noiri, Kento Kawasaki +11
The coherence of electron spin qubits in semiconductor quantum dots suffers mostly from low-frequency noise. During the last decade, efforts have been devoted to mitigate such nois…
