期刊論文
- Quantum Adiabatic Brachistochrone
A.T. Rezakhani, Wan-Jung Kuo, A. Hamma, D.A. Lidar, and P. Zanardi, Phys. Rev. Lett.
103, 080502 (2009)
DOI:10.1103/PhysRevLett.103.080502 (IF: 7.328 ; JIF Rank in SCIE: 6/71, Q1)
In this paper, we formulated a general time-optimal strategy which in principal can optimize
any quantum adiabatic algorithm for which the gap is known or can be estimated. The time-optimal
path obtained by this strategy is called Quantum Adiabatic Brachistochrone (QAB)
and was shown to yield better algorithmic performance than the conventional linear interpolation
path. In addition, we found that AQC can be recast naturally into a differential-geometric
framework. Specifically, a given family of physically controllable Hamiltonians can be equipped
with a Riemannian structure, along with a metric induced by the adiabatic evolution. Therefore,
the problem of finding QAB (the time-optimal path) for a given computational problem
is equivalent to finding the geodesic (the shortest path on the Riemannian manifold). This
geometric approach not only gives new insight into AQC but also allows us to apply existing
powerful tools of differential geometry to it. - Quadratic Dynamical Decoupling: Universality Proof and Error Analysis

Quadratic DD (QDD) which concatenates two layers of UDD is currently a near-optimal pulse
sequence for suppression of one qubit general decoherence. Complete analytical proof of the
actual performance of QDD was absent and was challenging due to the non-equidistant UDD
(QDD’s recursive unit) pulse intervals which makes the analysis non-trivial and difficult. In
this work, we provided a rigorous comprehensive proof of the actual performance of the generalized
version of QDD, where the orders of its inner and outer UDD layers, N1 and N2, can
be different. We analyzed thoroughly how each UDD layer interferes with each other, which
consequently identifies the region of N1 and N2 that QDD scheme cannot achieve its full suppression
potential. Moreover, the various interesting performance effects related to the parities
and relative magnitudes of N1 and N2 are found. Our proof also indicates that QDD sequence
is also a universal DD sequence for the generic bath with high-frequency dominated spectrum,
namely, its near-optimal performance is insensitive to the details of the noise environment. - Universality Proof and Error Analysis of Nested Uhrig Dynamical Decoupling

NUDD scheme, which nests multiple layers of UDD sequences, is a much more efficient (though
far from optimal) scheme, compared to other known DD schemes, for general multi-qubit decoherence
suppression. In this paper, the universality and performance of NUDD sequence
with ”general pulses” is rigorously proven and studied with compact and abstract formulation.
Moreover, the single-axis error type in our QDD paper is also generalized to a more general
concept. The explicit formula for the decoupling order of each error type is given, which shows
explicitly how the parities and relative magnitudes of UDD orders affect the suppression of
different types of errors. We also discover that the error cancellation mechanism relates to the
group structure underneath the error types. - HM and THM interactions in bentonite engineered barriers for nuclear waste disposal
