Detection of many-body entanglement partitions in a quantum computer
Albert Rico, Dmitry Grinko, Robin Krebs +1
We present a method to detect entanglement partitions of multipartite quantum systems, by exploiting their inherent symmetries. Structures like genuinely multipartite entanglement,…
Witnessing genuine multipartite entanglement in phase space with controlled Gaussian unitaries
Lin Htoo Zaw, Jiajie Guo, Qiongyi He +2
Many existing genuine multipartite entanglement (GME) witnesses for continuous-variable (CV) quantum systems typically rely on quadrature measurements, which are challenging to imp…
Sufficient Wigner Negativity Implies Genuine Multipartite Entanglement
Lin Htoo Zaw, Jiajie Guo, Qiongyi He +2
Wigner negativity and genuine multipartite entanglement (GME) are key nonclassical resources that enable computational advantages and broader quantum-information tasks. In this wor…
All three-angle variants of Tsirelson's precession protocol, and improved bounds for wedge integrals of Wigner functions
Lin Htoo Zaw, Valerio Scarani
Tsirelson's precession protocol is a nonclassicality witness that can be defined for both discrete and continuous variable systems. Its original version involves measuring a preces…
Certifying the quantumness of a nuclear spin qudit through its uniform precession
Arjen Vaartjes, Martin Nurizzo, Lin Htoo Zaw +16
Spin precession is a textbook example of dynamics of a quantum system that exactly mimics its classical counterpart. Here we challenge this view by certifying the quantumness of ex…
Even-parity precession protocol for detecting nonclassicality and entanglement
Jinyan Chen, Jackson Tiong, Lin Htoo Zaw +1
We introduce an even-parity precession protocol that can detect the nonclassicality of some quantum states using only measurements of a uniformly-precessing variable at different p…
Certifiable Lower Bounds of Wigner Negativity Volume and Non-Gaussian Entanglement with Conditional Displacement Gates
Lin Htoo Zaw
In circuit and cavity quantum electrodynamics devices where control qubits are dispersively coupled to high-quality-factor cavities, characteristic functions of cavity states can b…
Tsirelson's Inequality for the Precession Protocol is Maximally Violated by Quantum Theory
Lin Htoo Zaw, Mirjam Weilenmann, Valerio Scarani
The precession protocol involves measuring , the probability that a uniformly precessing observable (like the position of a harmonic oscillator or a coordinate undergoing spat…
Certification of genuine multipartite entanglement in spin ensembles with measurements of total angular momentum
Khoi-Nguyen Huynh-Vu, Lin Htoo Zaw, Valerio Scarani
We introduce entanglement witnesses for spin ensembles which detect genuine multipartite entanglement using only measurements of the total angular momentum. States that are missed…
A Witness of GHZ Entanglement Using Only Collective Spin Measurements
Lin Htoo Zaw, Khoi-Nguyen Huynh-Vu, Valerio Scarani
Of existing entanglement witnesses that utilize only collective measurements of a spin ensemble, not all can detect genuine multipartite entanglement (GME), and none can detect Gre…
Role of Dilations in Reversing Physical Processes: Tabletop Reversibility and Generalized Thermal Operations
Clive Cenxin Aw, Lin Htoo Zaw, Maria Balanzó-Juandó +1
Irreversibility, crucial in both thermodynamics and information theory, is naturally studied by comparing the evolution -- the (forward) channel -- with an associated reverse -- th…
Dynamics-based quantumness certification of continuous variables using time-independent Hamiltonians with one degree of freedom
Lin Htoo Zaw, Valerio Scarani
Dynamics-based certification of quantumness is an approach to witnessing the nonclassical character of some continuous-variable states, under the assumption that their dynamics is…

Pooja Jayachandran, Lin Htoo Zaw, Valerio Scarani
We introduce a family of entanglement witnesses for continuous variable systems, which rely on the sole assumption that their dynamics is that of coupled harmonic oscillators at th…

Lin Htoo Zaw, Clive Cenxin Aw, Zakarya Lasmar +1
Building on work by Tsirelson, we present a family of protocols that detect the nonclassicality of suitable states of a single quantum system, under the sole assumption that the me…
Sculpting bosonic states with arithmetic subtractions
Zaw Lin Htoo, Zakarya Lasmar, Chihuan Nguyen +4

Ghost factors in Gauss-sum factorization with transmon qubits
Lin Htoo Zaw, Yuanzheng Paul Tan, Long Hoang Nguyen +8
A challenge in the Gauss sums factorization scheme is the presence of ghost factors - non-factors that behave similarly to actual factors of an integer - which might lead to the mi…

MengKe Feng, Lin Htoo Zaw, Teck Seng Koh
The implementation of high fidelity two-qubit gates is a bottleneck in the progress towards universal quantum computation in semiconductor quantum dot qubits. We study capacitive c…
