Quantum computing is no longer a distant curiosity; it’s moving from theory to practical pilots and real enterprise impact. Instead of relying solely on binary states, quantum systems utilize superposition and entanglement to perform massively parallel calculations. The promise: Exponential speedups for workloads that overwhelm classical systems.
DXC Technology has been testing the potential of quantum machine learning (QML) and simulation for years, building proofs of concept with clients and partners. This work illustrates how quantum technology can tackle data bottlenecks and accelerate AI (even with today’s limited hardware), while laying a foundation for what’s coming next.
One proving ground was the 2024 Airbus BMW Quantum Computing Challenge (ABQCC). DXC teamed up with QuanIT and Kipu Quantum to propose two solutions:
This project demonstrated how quantum can enhance AI, particularly where data scarcity limits progress. As a result, our joint team was named a finalist in the autonomy stream.
Training self-driving systems requires huge datasets. Simulation helps, but it can’t fully replace real-world recordings under varied conditions, e.g., the same street at noon and midnight. Consequently, the challenge was to transform images across conditions so that models can learn safely and reliably.
That’s where quantum generative adversarial networks (qGANs) come in. By fusing classical GANs with quantum algorithms, DXC’s team showed it’s possible to generate convincing day-to-night (or night-to-day) transformations without needing duplicate real-world captures.
The architecture pairs a standard neural network generator with a quantum discriminator. The generator produces synthetic images, while the discriminator (running on a quantum circuit) compares them to originals and refines the results. Key steps include:
Encoding the image into quantum states
Running quantum operations (such as Fourier transforms or controlled-SWAP gates)
Measuring output and decoding results back into classical form

DXC’s team built this on AWS Braket with hybrid jobs; however, the approach is portable to other platforms, such as IBM Qiskit or CUDA-Q-based simulators.
The experiments confirmed that hybrid quantum-classical setups can work today, even with limited quantum hardware.

Three takeaways:
Convergence: Loss functions improved significantly within 200 epochs, with more qubits (4, 8, 16) speeding up convergence.
Performance trade-offs: Local simulators were fastest but capped at around 20 qubits. Real quantum backends, such as those provided by Braket (like Rigetti Ankaa-3 and IQM Garnet), had slower runtimes and limited uptime.
Hybrid dependence: Training leaned heavily on GPUs, showing that classical horsepower still carries most of the load while quantum provides targeted boosts.
The tests also highlighted a significant reality. Encoding and decoding data into quantum states eats into expected gains. However, that doesn’t erase the value; it just means hardware maturity and smarter pipelines will matter just as much as algorithms.
Quantum is not plug-and-play yet. CIOs and architects weighing their options should consider the following:
Hardware access: Real QPUs are scarce, with limited uptime and varying reliability across providers.
Integration overhead: Data encoding and hybrid job orchestration add friction.
Skills gap: Successful projects demand teams that blend quantum physics, ML and domain knowledge.
The path is clear. Each jump in qubit count and stability expands what’s feasible, moving quantum closer to mainstream IT strategy.
DXC’s work in the ABQCC and beyond shows that QML and simulation are no longer just science projects. They’re early-stage tools with real enterprise potential.
The quantum journey may be a bumpy ride, but the rewards could be transformative.
For CIOs and IT strategists, now is the time to get familiar, identify relevant workloads and build multidisciplinary teams that can translate quantum’s promise into better business outcomes.
DXC Technology teamed up with QuanIT and Kipu Quantum to propose a quantum-enhanced autonomy solution. The joint team was named a finalist for demonstrating how to use GenAI and quantum models to create realistic training images for autonomous vehicles and aircraft.
Experimentation is now possible: Cloud services like AWS Braket, CUDA-Q and IBM Qiskit enable teams to run small quantum workloads alongside classical ML.
Hybrid is the workable model: Expect classical and quantum to work in tandem for the foreseeable future.
Use cases are emerging: From safer autonomy to faster financial modeling, early pilots are showing where quantum delivers unique value.
