Summary
We developed a new protocol to speed up quantum state engineering in open quantum systems. This method, the inverse incoherent engineering protocol, achieves perfect fidelity for preparing entangled states in two-qubit systems.
Area of Science:
- Quantum Physics
- Quantum Information Science
Background:
- Open quantum systems are challenging for quantum state control due to decoherence.
- Adiabatic evolution is typically slow, limiting practical applications.
Purpose of the Study:
- To develop a protocol for constructing shortcuts to adiabaticity in open quantum systems.
- To engineer quantum states with high fidelity using a novel approach.
Main Methods:
- Utilized dynamical invariants of open quantum systems.
- Designed a driver Hamiltonian for the adiabatic decoherence free subspaces (TDFs) scheme.
- Applied the inverse incoherent engineering protocol to a two-qubit system interacting with a squeezed field.
Main Results:
- Successfully engineered quantum states from initial to target states with perfect fidelity.
- Demonstrated the protocol's effectiveness in both adiabatic and nonadiabatic regimes.
- Prepared maximally entangled states in a two-qubit system.
Conclusions:
- The proposed inverse incoherent engineering protocol offers an efficient method for quantum state preparation in open systems.
- This technique accelerates adiabatic processes, overcoming limitations of traditional methods.
- The protocol shows promise for applications in quantum information processing and quantum computing.

The z-transform is a fundamental tool in digital signal processing, enabling the analysis of discrete-time systems through its various properties. It is an invaluable tool for analyzing discrete-time systems, offering a range of properties that simplify complex signal manipulations. One fundamental property is linearity. For any two discrete-time signals, the z-transform of their linear combination equals the same linear combination of their individual z-transforms. This property is essential...

A system is linear if it displays the characteristics of homogeneity and additivity, together termed the superposition property. This principle is fundamental in all linear systems. Linear time-invariant (LTI) systems include systems with linear elements and constant parameters.
The input-output behavior of an LTI system can be fully defined by its response to an impulsive excitation at its input. Once this impulse response is known, the system's reaction to any other input can be...

Control systems are everywhere in contemporary society, influencing diverse applications from aerospace to automated manufacturing. These systems can be found naturally within biological processes, such as blood sugar regulation and heart rate adjustment in response to stress, as well as in man-made systems like elevators and automated vehicles. A control system is essentially a network of subsystems and processes that collaboratively convert specific inputs into desired outputs.

Mechanical systems are analogous to to electrical networks where springs and masses play similar roles to inductors and capacitors, respectively. A viscous damper in mechanical systems functions similarly to a resistor in electrical networks, dissipating energy. The forces acting on a mass in such systems include an applied force in the direction of motion, counteracted by forces from the spring, a viscous damper, and the mass's acceleration. This interplay of forces is mathematically...

Electromechanical systems are intricate configurations that effectively combine electrical and mechanical elements to achieve a desired outcome. Central to many of these systems is the DC motor, a device that converts electrical energy into mechanical motion, enabling various applications ranging from simple fans to complex robotic mechanisms.

4.9K
Sound waves can be modeled either as longitudinal waves, wherein the molecules of the medium oscillate around an equilibrium position, or as pressure waves. When two identical waves from the same source superimpose on each other, the combination of two crests or two troughs results in amplitude reinforcement known as constructive interference. If two identical waves, that are initially in phase, become out of phase because of different path lengths, the combination of crests with troughs...
