# Anna meets Leonard

The days following their dinner seemed to be permeated by a special tension that Anna felt in every encounter with Leonard. Their conversations, which at first seemed merely casual and professional, gained a depth that surprised her. It was as if an invisible thread had been woven between them, drawing them a little closer with each conversation.

One afternoon, they sat in Anna's glass booth. The screens flickered with the streams of data before them. The sounds of the server rooms were like the hum of a distant world, barely noticeable in the silence of their collaboration.

“There are more and more of these small anomalies,” Anna murmured as she analyzed the data packets. “Almost as if someone is deliberately trying to circumvent the surveillance systems.”

Leonard leaned closer, his gaze following the sequence of numbers. "Perhaps there really is someone looking for loopholes. Or it's simply a flaw in the algorithm – AI isn't as perfect as they claim."

Anna heard a subtle emphasis in his voice. "So you don't believe that surveillance is all-powerful?"

“No system is infallible,” Leonard replied, his eyes remaining fixed on the screen. “There’s always a loophole. You just have to know how to find it.”

Anna nodded slowly. A thought began to take root in her mind—fascinating and frightening at the same time. “What if we could create our own vulnerability?” she asked quietly, as if she feared that the walls themselves might be listening. “A communication channel that evades the surveillance algorithms?”

Leonard turned to her. His smile was both challenging and encouraging. “Quantum encryption,” he said, almost whispering. “The quantum computers at the ETZ are powerful enough to decode such messages. But if we find the right method, it might be possible to establish a channel that goes undetected.”

A wave of excitement washed over Anna. The possibility of creating a communications network that defied control was more than a technical challenge—it was a sign of hope. “We could disguise it as an experiment,” she suggested, her voice now more confident. “A research project to improve security protocols. Officially, at least.”

Leonard nodded, his eyes sparkling with enthusiasm. "And unofficially, we're creating a way to communicate independently."

The idea began to take shape. They thought about the details, designed algorithms, and analyzed security vulnerabilities. Every conversation, every moment spent together brought them closer – but also closer to the dangerous reality that they wanted to create something that broke the rules.

It was a risky plan. But for Anna, it suddenly felt more alive than anything she had ever done. Their eyes met more and more often. The closeness between them wasn't just due to their work together. It was an unspoken bond of curiosity and quiet rebellion.

In the following days, they often worked late. While the rest of the ETZ gradually settled down, they sat hunched over their plans during the quiet hours of the night, their faces illuminated by the screens. Their fingers flew across the keyboards in the darkness. Sometimes their hands touched—small, meaningful touches that awakened a feeling of intimacy they hardly dared to acknowledge.

Anna sensed something bigger was brewing, a change that was palpable in her work and in her life. Leonard had not only found his way to a new communication network – but also to her heart.

Leonard sat alone in the darkened laboratory of the ETZ. The bluish glow of the monitor displays and the soft glow of the circuits illuminated the room. The clock showed well past midnight.

Before him lay a complex network of quantum processors, lasers, and optical circuits, which he had carefully adjusted over the past few weeks. His goal was a tap-proof communication network. The existing hardware was insufficient. He had to synchronize the light pulses in the optical circuits so precisely that even the slightest interference was avoided.

Using the tip of a screwdriver, he adjusted a tiny lens. Every move had to be precise. The idea of working at night was risky – but it was the only way to hide this secret work from the prying eyes of the administrators.

When Leonard finally checked the last circuit, a wave of relief washed over him. Initial tests showed that his modifications had reduced interference. The hardware was now capable of sending and receiving encrypted signals without InSim's standard algorithms detecting the patterns. At least in theory.

Now came the critical part: testing had to be done – and for that he needed Anna's help.

Leonard leaned back and took a deep breath. Then he reached for his tablet and wrote a short message to Anna:

“Shall we meet at midnight in the lab? I have something we should try. It might be risky, but I think it’s the right moment.”

With one last glance at the now silent circuits, he sent the message. His heart was beating faster. He knew he was putting Anna in a dangerous situation – but he trusted in her determination and courage.

The door opened with a soft hiss. Anna stepped inside, her coat draped over her shoulder, her hair slightly tousled by the night wind. Her eyes glittered in the dim light.

"I thought I was the only one who sneaks in here at night," she said with a slight smile. "You never told me you had a secret lab."

Leonard returned the smile. "I guess I improvised it. But I need your help. I think we have something here that could work—a way to make ourselves invisible. To the surveillance algorithms."

Anna stepped closer and bent over the hardware. "So you think we could build a network that runs outside the regular system?"

"That's the idea. But we need to test it thoroughly. There's a risk we'll be discovered. If you don't want to risk it, I understand."

Anna shook her head. "I'm here, aren't I? So let's see what we can do with this."

Leonard activated the system. The lights on the devices illuminated one after the other. The first encrypted packets were sent. The test transmission was a quote from an old poem: Freedom lies not in the world, but in our hearts.

“Look here,” Leonard said quietly, pointing to a section of the code. “These are the current logs of the surveillance systems. We sent a data packet that should theoretically be registered – but it doesn’t appear in any trace.”

Anna looked at him thoughtfully. "That means we've managed to stay under the radar. But what if they change the parameters?"

"Therefore, we must ensure that our signal is not only invisible, but also looks like something else. The quantum encryption must be disguised as noise, embedded in the existing data stream."

“That could work,” said Anna. “But we need more computing power for that. Perhaps we could discreetly use the capacities of other laboratories.”

Leonard smiled wryly. "A nighttime data heist? That sounds like a challenge." He leaned back. "But before we tackle that: Are you ready for a larger transfer?"

Anna nodded resolutely. "Let's give it a try. If we get discovered, at least it will be because we're daring to do something big."

They entered the commands for the next test sequence. Every second felt like an eternity. The hum of the equipment seemed to grow louder—then a sign that the transmission had gone undetected.

A soft sigh of relief swept through the room. Anna and Leonard exchanged a glance. It was more than the triumph of passing the test – it was their first adventure together, a secret alliance that bound them stronger with every risk.

“We should leave now,” Anna said. “Before the security guards arrive.”

Leonard nodded. "But perhaps we should discuss the next steps tomorrow evening – somewhere outside the lab."

Anna gave him a mischievous look. "Maybe. But let's go now."

Together they left the laboratory, their footsteps echoing in the dark corridors. The first step had been taken – the invisible network now existed, at least in their minds.
