So what's the carbon footprint of #NISQ?

MUDASSAR SALEEM Nov 10

In 2025, quantum computing is rapidly scaling up, bringing clearer architectures and a fierce push toward building logical qubits. Even though the NISQ era is still here, researchers are focused on boosting fidelity and managing the heavy error-correction demands that stand between today’s systems and real quantum advantage. #QuantumComputing #NISQ #TechLeadership #QuantumTech #QuantumChemistry #QAOA #FutureOfTech

Adaptive Trotterization for Time-Dependent Hamiltonian Quantum Dynamics Using Piecewise Conservation Laws

Our new paper introduces an adaptive Trotterization algorithm to tackle time-dependent Hamiltonians in digital quantum simulation. We propose piecewise conserved quantities to control and estimate errors & error accumulation. Read more here in this PRL:

Adaptive Trotterization for Time-Dependent Hamiltonian Quantum Dynamics Using Piecewise Conservation Laws

Digital quantum simulation relies on Trotterization to discretize time evolution into elementary quantum gates. On current quantum processors with notable gate imperfections, there is a critical trade-off between improved accuracy for finer time steps, and increased error rate on account of the larger circuit depth. We present an adaptive Trotterization algorithm to cope with time dependent Hamiltonians, where we propose a concept of piecewise ``conserved'' quantities to estimate errors in the time evolution between two (nearby) points in time; these allow us to bound the errors accumulated over the full simulation period. They reduce to standard conservation laws in the case of time independent Hamiltonians, for which we first developed an adaptive Trotterization scheme [H. Zhao et al., Making Trotterization adaptive and energy-self-correcting for NISQ devices and beyond, PRX Quantum 4, 030319 (2023).]. We validate the algorithm for a time dependent quantum spin chain, demonstrating that it can outperform the conventional Trotter algorithm with a fixed step size at a controlled error.

Making Trotterization Adaptive and Energy-Self-Correcting for NISQ Devices and Beyond

Digital quantum simulation requires time discretization by means of Trotterization. A finer time step improves simulation precision but inevitably leads to increased experimental errors for today’s noisy intermediate-scale quantum computers. Check out in our recent publication how to make Trotterization adaptive:
