Shot-Efficient ADAPT-VQE via Reused Pauli Measurements and Variance-Based Shot Allocation
Azhar Ikhtiarudin, Gagus Ketut Sunnardianto, Fadjar Fathurrahman +2
The Adaptive Variational Quantum Eigensolver (ADAPT-VQE) is a promising approach for quantum algorithms in the Noisy Intermediate-Scale Quantum (NISQ) era, offering advantages over…
Quantum entanglement as an extremal Kirkwood-Dirac nonreality
Agung Budiyono
Understanding the relationship between various different forms of nonclassicality and their resource character is of great importance in quantum foundation and quantum information.…
Operational interpretation and estimation of quantum trace-norm asymmetry based on weak value measurement and some bounds
Agung Budiyono
The asymmetry of a quantum state relative to a translational group is a central concept in many areas of quantum science and technology. An important and geometrically intuitive me…
Quantum coherence as asymmetry from complex weak values
Agung Budiyono, Mohammad K. Agusta, Bagus E. B. Nurhandoko +1
Quantum coherence as an asymmetry relative to a translation group generated by a Hermitian operator, is a necessary resource for the quantum parameter estimation. On the other hand…
Quantifying quantum coherence via nonreal Kirkwood-Dirac quasiprobability
Agung Budiyono, Hermawan K. Dipojono
Kirkwood-Dirac (KD) quasiprobability is a quantum analog of phase space probability of classical statistical mechanics, allowing negative or/and nonreal values. It gives an informa…
Fast-forward adiabatic quantum dynamics of XY spin model on three spin system
Iwan Setiawan, Riska Ekawita, Ryan Sugihakim +1
We discussed a method to accelerate an adiabatic quantum dynamics of XY spin model by using the fast-forward method proposed by Masuda and Nakamura. The Accelerated scheme is const…
Conservation of correlation in measurement underlying the violation of Bell inequalities and a game of joint mapping
Agung Budiyono
What compels quantum measurement to violate the Bell inequalities? Suppose that regardless of measurement, one can assign to a spin- particle (qubit) a definite value…
General quantum correlation from nonreal values of Kirkwood-Dirac quasiprobability over orthonormal product bases
Agung Budiyono, Bobby E. Gunara, Bagus E. B. Nurhandoko +1
We propose a characterization and a quantification of general quantum correlation which is exhibited even by a separable (unentangled) mixed bipartite state in terms of the nonclas…
A prescreening method for variational quantum state eigensolver
Hikaru Wakaura, Andriyan B. Suksmono
The development of Fault-Tolerant Quantum Computer (FTQC) gradually raises a possibility to implement the Quantum Phase Estimation (QPE) algorithm. However, QPE works only for norm…
Quantum uncertainty as classical uncertainty of real-deterministic variables constructed from complex weak values and a global random variable
Agung Budiyono, Hermawan K. Dipojono
What does it take for real-deterministic c-valued (i.e., classical, commuting) variables to comply with the Heisenberg uncertainty principle? Here, we construct a class of real-det…

Consider a statistical model with an epistemic restriction such that, unlike in classical mechanics, the allowed distribution of positions is fundamentally restricted by the form o…
Estimation independence as an axiom for quantum uncertainty
