This work focuses on the development of nano spinel ferrite-based electrodes to enhance supercapacitor performance. Spinel ferrite nanoparticles are utilized due to their high conductivity, large surface area, and low cost. The materials are synthesized using a hydrothermal method with different doping ratios, and their electrochemical performance is evaluated using various techniques. The results demonstrate improved capacitance and excellent cycling stability, indicating that vanadium-doped spinel ferrites are promising candidates for advanced energy storage applications.

 

Deutsch's algorithm, proposed by David Deutsch in 1985, was the first quantum algorithm to demonstrate a clear computational advantage over classical methods. The problem is simple: given an unknown binary function f:{0,1}→{0,1}, determine whether it is constant (f(0)=f(1)) or balanced (f(0)≠f(1)) using as few evaluations as possible. Classically, this requires two function calls, one for f(0) and one for f(1). Deutsch's algorithm accomplishes the same task with only a single query by exploiting quantum parallelism and phase kickback. The algorithm prepares a superposition of both inputs, applies the quantum oracle U_f once, and uses interference to extract the global property. A final measurement reveals with certainty whether the function is constant or balanced. Though simple, Deutsch's algorithm illustrates the core principles of quantum computing; superposition, interference, and quantum parallelism, and laid the foundation for later algorithms such as Deutsch–Jozsa, Shor's, and Grover's. This seminar will present the circuit, walk through the state evolution, and discuss its historical significance.
