A class of entangling gates for trapped atomic ions is studied and the use of numeric optimization techniques to create a wide range of fast, error‐robust gate constructions is demonstrated. A numeric optimization framework is introduced targeting maximally‐ and partially‐entangling operations on ion pairs, multi‐ion registers, multi‐ion subsets of large registers, and parallel operations within a single register. Ions are assumed to be individually addressed, permitting optimization over… 
Numerical Engineering of Robust Adiabatic Operations
Adiabatic operations are powerful tools for robust quantum control in numerous fields of physics, chemistry and quantum information science. The inherent robustness due to adiabaticity can, however,
Programming the full stack of an open-access quantum computer
TLDR
This work presents a new quantum programming language called ‘Quala’ that enables true full-stack programming of quantum hardware and intends for this language to bridge the gap between circuit-level programming and physical operations on real hardware while maintaining full transparency in each level of the stack.

More speed out of the quantum gate
Quantum gates on trapped ions may be quicker and more reliable owing to squeezing of their vibrational motion. A threefold drop in operation time shows potential for applications in quantum
Robust entanglement by continuous dynamical decoupling of the J-coupling interaction
We propose a σ z ⊗ σ z laser-free entangling gate which uses the intrinsic J-coupling of ions in a static magnetic gradient. Dephasing of the interaction is suppressed by means of continuous
Scalable hyperfine qubit state detection via electron shelving in the 2D5/2 and 2F7/2 manifolds in 171Yb+
Qubits encoded in hyperfine states of trapped ions are ideal for quantum computation given their long lifetimes and low sensitivity to magnetic fields, yet they suffer from off-resonant scattering
Software tools for quantum control: improving quantum computer performance through noise and error suppression
TLDR

Phase-Modulated Entangling Gates Robust to Static and Time-Varying Errors
Entangling operations are among the most important primitive gates employed in quantum computing and it is crucial to ensure high-fidelity implementations as systems are scaled up. We experimentally
Parallel entangling operations on a universal ion-trap quantum computer

Parallel two-qubit entangling gates are realized in an array of fully connected trapped-ion qubits, achieving a full-adder operation on a quantum processor with an average fidelity of 83.3 per cent.
Global entangling gates on arbitrary ion qubits
TLDR
This work proposes and implements a scalable scheme for realizing global entangling gates on multiple 171Yb+ ion qubits by coupling to multiple motional modes through modulated laser fields and develops a system with fully independent control capability on each ion.
Trapped ion scaling with pulsed fast gates
Fast entangling gates for trapped ions offer vastly improved gate operation times relative to implemented gates, as well as approaches to trap scaling. Gates on neighbouring ions only involve local
Phase-modulated decoupling and error suppression in qubit-oscillator systems.
TLDR
It is demonstrated how the exclusive use of discrete shifts in the phase of the field moderating the qubit-oscillator interaction is sufficient to both ensure multiple oscillator modes are decoupled and to suppress the effects of fluctuations in the driving field.
Resilient Entangling Gates for Trapped Ions.
TLDR
This work experimentally demonstrates how a new type of Mølmer-Sørensen gate protects against infidelity caused by heating of the motional mode used during the gate, and shows how the same technique simultaneously provides significant protection against slow fluctuations and mis-sets in the secular frequency.
Fast quantum logic gates with trapped-ion qubits
TLDR
This work demonstrates entanglement generation for gate times as short as 480 nanoseconds—less than a single oscillation period of an ion in the trap and eight orders of magnitude shorter than the memory coherence time measured in similar calcium-43 hyperfine qubits.

An optimized frequency-modulated 2-qubit gate that can suppress errors to less than 0.01% and is robust against frequency drifts over ±1  kHz is obtained.
Experimental comparison of two quantum computing architectures
TLDR
It is shown that quantum algorithms and circuits that use more connectivity clearly benefit from a better-connected system of qubits, and suggested that codesigning particular quantum applications with the hardware itself will be paramount in successfully using quantum computers in the future.
