It's been so long since I last drew an E/R diagram, I got things mixed up with UML class diagrams

वैकुण्ठमान चतुर्वेदी

वैकुण्ठमान चतुर्वेदीको जवानी तम्बाखुको आदत र चुरोटको धुवाँमा उड्यो। कसैको अर्ती उपदेश नसुन्ने, आफ्नै अहङ्कारमा रमाउने उनको बानी थियो। 'के हुन्छ त मलाई?' भन्ने दम्भ पालेर उनी खराब आदत पालनमा नै रहे।

उमेर छँदा त शरीरले खप्यो, खासै समस्या देखिएन। तर, उमेर ढल्किँदै जाँदा उनको फोक्सोमा दमले 'पिआर पायो', र बिस्तारै निमोनियाले गाँज्यो। त्यसमाथि सहरको विषाक्त वायुप्रदूषण! स्वस्थ मान्छे त बिरामी पर्न थालेको त्यो बेला, एक साँझ बाहिर निस्किएका वैकुण्ठमानलाई बेमौसमी असिनापानीले यसरी चुट्यो कि उनी सडकमै इन्तु न चिन्तु भएर ढले।

एकातिर बुढ्यौलीको जर्जर शरीर, अर्कातिर दम र निमोनियाको व्यथा, त्यसमाथि चिसो असिनापानीको निर्मम चुटाइ। अब उनलाई सघन उपचार, उचित खानपान र स्वच्छ वातावरणको जरुरत थियो।

श्वासप्रश्वासको सङ्कट झेलिरहेका चतुर्वेदीजीलाई अब छातीरोग विशेषज्ञकहाँ लैजाने कि कुनै कस्मेटिक सर्जनकहाँ? फोक्सो चिलिम फर्किन लागेको बिरामीलाई अक्सिजन र एन्टिबायोटिक छाडेर अनुहारको चाउरी तन्काउन प्लास्टिक सर्जनकहाँ लैजानु भनेको सिधै यमलोकको टिकट थमाइदिनु हो।

आज नेकपा एमाले ठ्याक्कै वैकुण्ठमान चतुर्वेदीकै नियति बाँचिरहेको छ। आफ्नै दम्भ र खराब राजनीतिक आदतका कारण पार्टी भित्रभित्रै थलिएको छ। जनमानसमा साख नराम्ररी गिरेको छ भने चुनावमा व्यहोरेको लज्जास्पद हारको चोट आलै छ। अझ जेनजी आन्दोलनमाथि दमन गरेको आरोपमा पार्टी अध्यक्ष नै हिरासतमा पुगेपछि त एमालेको राजनीतिक निमोनिया अन्तिम चरणमा पुगेको छ। पार्टीका सारा अङ्गहरू शिथिल बनेका छन्, र जनताको विश्वासको अक्सिजन पूर्ण रूपले टुट्ने संघारमा छ।

यस्तो जीवनमरणको दोसाँधमा उभिएको बेला, केही फाइँफुट्टा काजी, कजिनीहरु अचम्मको कुरा गर्दैछन्– ' स्वर्गीय नेम्वाङजीको छोरा ह्यान्डसम छन् । उनलाई संसदीय दलको नेता बनाएको भए त्यो झिल्के अनुहारको प्रतापले एमाले रातारात तंग्रिन्थ्यो । बर्वादै भयो !' निमोनियाले थलिएका वैकुण्ठमानलाई प्लास्टिक सर्जरी गरेर निको पार्ने कुरा जति हास्यास्पद छ, एमालेको वर्तमान सङ्कटलाई एउटा 'ह्यान्डसम' अनुहारले पार लगाउँछ भन्नु त्यति नै छ।

एमालेलाई अहिले अनुहारको 'मेकअप' होइन, वैचारिक र साङ्गठनिक 'सर्जरी' चाहिएको छ। आफ्ना विगतका कमजोरीहरूको निर्मम समीक्षा, खराब आदतको तिलाञ्जली र जनभावना बुझ्ने सक्षम नेतृत्वबिना यो सङ्कट टर्नेवाला छैन। यो राजनीतिक प्रदूषणका बीच जनतासँग टुटेको सम्बन्धको डोरी फेरि नजोड्ने र एउटा झिल्के अनुहार अघि सारेर पार्टी तंग्र्याउँछु भन्ने भ्रम पाल्ने हो भने, निश्चित छ– कस्मेटिक सर्जनको टेबलमा वैकुण्ठमानको प्राण पखेरु उडेजस्तै, एमालेको पनि सधैंका लागि 'वैकुण्ठवास' हुनेछ।

QuanUML: Development Of Quantum Software Engineering

Researchers have invented QuanUML, a new version of the popular Unified Modelling Language (UML), advancing quantum software engineering. This new language is designed to make complicated pure quantum and hybrid quantum-classical systems easier to model, filling a vital gap where strong software engineering methods have not kept pace with quantum computing hardware developments.

The project, led by Shinobu Saito from NTT Computer and Data Science Laboratories and Xiaoyu Guo and Jianjun Zhao from Kyushu University, aims to improve quantum software creation by adapting software design principles to quantum systems.

Bringing Quantum and Classical Together

Quantum software development is complicated by quantum mechanics' stochastic and non-deterministic nature, which classical modelling techniques like UML cannot express. QuanUML directly solves this issue by adding quantum-specific features like qubits, the building blocks of quantum information, and quantum gates operations on qubits to the conventional UML framework. It also shows entanglement and superposition.

QuanUML advantages include

By providing higher-level abstraction in quantum programming, QuanUML makes it easier and faster for developers to construct and visualise complex quantum algorithms. Unlike current methods, which require developers to work directly with low-level frameworks or quantum assembly languages.

Leveraging Existing UML Tools: QuanUML expands UML principles to make it easy to integrate into software development workflows. Standard UML diagrams, like sequence diagrams, visually represent quantum algorithm flow, improving comprehension and communication.

A major benefit of QuanUML is its comprehensive support for model-driven development (MDD). Developers can create high-level models of quantum algorithms instead of focussing on implementation details. This structured and understandable representation increases collaboration and reduces errors, speeding up quantum software creation and enabling automated code generation.

The language's modelling features can be used to visualise quantum phenomena like entanglement and superposition using modified UML diagrams. Visual clarity aids algorithm comprehension and debugging, which is crucial for gaining intuition in a difficult field. Quantum gates are described as messages between lifelines, whereas qubits are represented as <> lifelines to differentiate between single-qubit asynchronous communications and multi-qubit synchronous/grouping messages and control relationships. Quantum experiments with probabilistic state collapses use asynchronous signals to end qubit lifelines.

QuanUML simplifies theory-to-practice transitions by combining algorithmic design with quantum hardware platform implementation. Abstracting low-level implementation details allows developers focus on algorithm logic, boosting design quality and development time.

Two-Stage Workflow: QuanUML uses high-level and low-level models. High-level modelling of hybrid systems uses UML class diagrams with a <> archetype to reflect their architecture. Low-level modelling changes UML sequence diagrams to portray qubits, quantum gates, superposition, entanglement, and measurement processes utilising stereotypes and message types to study quantum algorithms and circuits.

Practical Examples and Future Vision

Through detailed case studies using dynamic circuits and Shor's Algorithm, QuanUML demonstrated its effectiveness in modelling successful long-range entanglement.

QuanUML efficiently models dynamic quantum circuits' classical control flow integration using UML's Alt (alternative) fragment to visualise qubit initialisation, gate operations, mid-circuit measurements, and classical feed-forward logic.

QuanUML can handle sophisticated hybrid algorithms like Shor's Algorithm by mixing high-level class diagrams (using the <> archetype for quantum classes) with intricate low-level sequence diagrams. It manages complexity by modelling abstract sub-quantum computations.

QuanUML has a more comprehensive software modelling framework, deeper low-level modelling capabilities, and demonstrated element efficiency in some quantum algorithms than Q-UML and the Quantum UML Profile due to its accurate representation of multi-qubit gate control relationships.

QuanUML provides a framework for designing, visualising, and evaluating complex quantum algorithms, which the authors think will help build quantum software. Future enhancements aim to expedite development and accelerate theoretical methodologies to real-world applications. Extensions include code generation for Qiskit, Q#, Cirq, and Braket quantum computing SDKs.

This unique strategy speeds up the design of complex quantum applications and promotes cooperation in quantum computing. The shift from direct coding to structured design indicates a major change in quantum software engineering.
