-= Hypothesis
+Can hardware specific Quantum Ansatz Search improve the performance of variational quantum eigensolvers
+better than hardware agnostic alternatives?
+
+== Hypothesis
+
+We think that knowing about the hardware constraints helps with improving the search results since
+transpilation often degrades the performance of hardware agnostic ansatze which will not be necessary
+when using an ansatz specific to the hardware.

+	abstract = {The limitations of noisy intermediate-scale quantum (NISQ) devices
+	            have motivated the development of variational quantum algorithms
+	            (VQAs), which are designed to potentially achieve quantum advantage
+	            for specific tasks. Quantum architecture search (QAS) algorithms
+	            play a critical role in automating the design of high-performance
+	            parameterized quantum circuits (PQCs) for VQAs. However, existing
+	            QAS approaches struggle with large search spaces, leading to
+	            substantial computational overhead when optimizing large-scale
+	            quantum circuits. Extensive empirical analysis reveals that circuit
+	            topology has a greater impact on quantum circuit performance than
+	            gate types. Based on this insight, we propose the topology-driven
+	            quantum architecture search (TD-QAS) framework, which first
+	            identifies optimal circuit topologies and then fine-tunes the gate
+	            types. In the fine-tuning phase, the QAS inherits parameters from
+	            the topology search phase, eliminating the need for training from
+	            scratch. By decoupling the large search space into separate
+	            topology and gate-type components, TD-QAS avoids exploring gate
+	            configurations within low-performance topologies, thereby
+	            significantly reducing computational complexity. Numerical
+	            simulations across various tasks, under both noiseless and noisy
+	            conditions, validate the effectiveness of the TD-QAS framework.
+	            This framework advances standard QAS algorithms by enabling the
+	            identification of high-performance quantum circuits while
+	            minimizing computational demands. These findings indicate that
+	            TD-QAS deepens our understanding of VQAs and offers broad potential
+	            for the development of future QAS algorithms.},
